umbrello (2.11.0) on KDE Platform 4.11.00 using Qt 4.8.5

- What I was doing when the application crashed:
Umbrello crash on startup. The console shows the following output:

If you self compiled umbrello  the line 

#23 UMLListViewItem::setIcon (this=0x7f7241b1d120, iconType=<optimized out>) at /home/portagetmp/portage/kde-base/umbrello-4.9.5/work/umbrello-4.9.5/umbrello/umbrello/umllistviewitem.cpp:467

which is 

/**
 * Set the pixmap corresponding to the given IconType.
 */
void UMLListViewItem::setIcon(Icon_Utils::IconType iconType)
{
467    QPixmap p = Icon_Utils::SmallIcon(iconType);
 468   QTreeWidgetItem::setIcon(0, QIcon(p));
}

let me assume that umbrello did not find an icon. 
To run a self compiled umbrello you should follow the instructions in the section "Source Code on Linux like operating systems" on http://umbrello.kde.org/installation.php. 

If this problem persists, feel free to reopen this bug.

As reported by backtrace I'm using umbrello 2.11 from Chakra official repository. I have downloaded source code and added a qdebug in void UMLListViewItem::setIcon(Icon_Utils::IconType iconType) and the error happens when iconType is "it_Folder_Orange" that is converted in "folder-orange" by Icon_Utils::toString(...). I have searched my filesystem for "folder-orange" and found:

/usr/share/icons/oxygen/22x22/places/folder-orange.png
/usr/share/icons/oxygen/16x16/places/folder-orange.png
/usr/share/icons/oxygen/128x128/places/folder-orange.png
/usr/share/icons/oxygen/256x256/places/folder-orange.png
/usr/share/icons/oxygen/32x32/places/folder-orange.png
/usr/share/icons/oxygen/64x64/places/folder-orange.png
/usr/share/icons/oxygen/48x48/places/folder-orange.png

And in the output I can read it's using it previously without crashing:

http://paste.chakra-project.org/5066/

So I fear the bug is triggered by something else.

I see. 
Unfortunally I cannot reproduce this problem on my system which is umbrello git tag 4.11.0,  qt 4.8.4, KDE 4.9.5. I also tried italian application language, but did not raise the error. 

May be a icon cache problem ? 

You may try to remove 

 ~/.kde4/cache-<hostname>/icon-cache.kcache  

and restart umbrello. If the icons are not installed correctly you will see then empty pages on the umbrello toolbar. 

BTW: Are you using a 32bit or 64 bit system ?

icon-cache.kcache trick didn't work. I'm using a 64bit system (kde 4.11, qt 4.8.5).

I tryed two others workarounds:
- first I replaced the code in UMLListViewItem::setIcon with the following

QIcon myIcon(QLatin1String("/usr/share/icons/oxygen/16x16/places/folder.png"));
QTreeWidgetItem::setIcon(0, myIcon);

result: crash.

- in the original code I commented out QTreeWidgetItem::setIcon(0, QIcon(p)) :

QPixmap p = Icon_Utils::SmallIcon(iconType);
//QTreeWidgetItem::setIcon(0, QIcon(p));

result: worked.

Very weird: I reverted the code and umbrello doesn't crash at start up but if I remove ~/.kde4/share/config/umbrellorc the bug returns. Seems that commenting that line is the only solution to run umbrello for the first time.

Can you confirm this?

P.S.
2 more files:
umbrellorc created on crash: http://paste.chakra-project.org/5073/
umbrellorc in correct start up: http://paste.chakra-project.org/5076/

> Can you confirm this? 
Unfortunally no

> umbrellorc in correct start up: http://paste.chakra-project.org/5076/
So when you remove 
[workbar]
ToolButtonStyle=IconOnly

from umbrellorc and start umbrello then umbrello crashes ? 

The workbar section is handled in 
void UMLApp::readOptions()
{
    // bar status settings
    toolBar("mainToolBar")->applySettings(m_config->group("toolbar"));
    // do config for work toolbar
    m_toolsbar->applySettings(m_config->group("workbar"));
    fileOpenRecent->loadEntries(m_config->group("Recent Files"));
    setImageMimeType(UmbrelloSettings::imageMimeType());
    resize(UmbrelloSettings::geometry());
}

Does it help to uncomment some of the workbar related applySettingsCall 

2: Do 

//QPixmap p = Icon_Utils::SmallIcon(iconType); 
QTreeWidgetItem::setIcon(0, QIcon());

work ?

No, works but it crashes removing

[General Options]
Geometry=947,549
autosavetime=5

the next umbrellorc doesn't contain any [General Options] section and in [Mainwindow] are added the two lines:

Height 1050=307
Width 1680=294

> Does it help to uncomment some of the workbar related applySettingsCall 
tryed various combinations, nothing works

> //QPixmap p = Icon_Utils::SmallIcon(iconType); 
> QTreeWidgetItem::setIcon(0, QIcon());
> 
> work ?

nope

As you tried this with 2 different umbrello versions I guess there must be a problem outside the umbrello code. 
Can you try to run 

KDEHOME=/tmp/kde-test-home/ umbrello

and report what happens ?

Sorry but this is the first version of umbrello I try, another guy opened this bug. Anyway, I tryed with KDEHOME=... and it's still crashing

> Sorry but this is the first version of umbrello I try, another guy opened this bug.
I see - Unfortunally the first reporter did not tell us if he had found the reason for this problem, so we have to take a deeper look into this issue.

What happens when you run

umbrello --export-formats

Do you see a list of file extensions similar to 

bmp
bw
dot
eps
epsf
epsi
ico
jp2
jpeg
jpg
pcx
pic
png
ppm
rgb
rgba
sgi
svg
tga
tif
tiff
xbm
xpm
xv

or does umbrello crash ?

Another idea would be to comment out the following lines in umlistview.cpp 

121 // connect(this, SIGNAL(itemCollapsed(QTreeWidgetItem*)), this, SLOT(slotCollapsed(QTreeWidgetItem*)));
122 // connect(this, SIGNAL(itemExpanded(QTreeWidgetItem*)), this, SLOT(slotExpanded(QTreeWidgetItem*)));

This will not trigger the setIcon call mentioned in the backtrace.

I have news: today I updated to 2.11.1 / kde 4.11.1 and umbrello doesn't crash anymore but some icons from gui are missing:

http://wstaw.org/m/2013/09/04/umbrello.png

If I'm not wrong, missing icons should be umbrello's ones. The chakra's umbrello package seems contain all required files, in right location:

http://paste.chakra-project.org/5114/

I tryed removing ~/.kde4/cache-<hostname>/icon-cache.kcache, but didn't solved. Then I tryed moving some files from /usr/share/apps/umbrello/pics/ to /usr/share/pixmaps/ and they showed in toolbar. Is "/usr/share/apps/umbrello/pics/" the right location or had to file a bug to chakra's packages maintainers?

fine

they may be installed into a wrong location, see below

> The chakra's  umbrello package seems contain all required files,  
good 
> in right location:
seems to be not the case 

> I tryed removing ~/.kde4/cache-<hostname>/icon-cache.kcache, but didn't solved. 
good, would help for corrupted cache 

> Then I tryed moving some files from /usr/share/apps/umbrello/pics/
> to /usr/share/pixmaps/ and they showed in toolbar. 
indicates wrong install location

The correct location could be retrieved with 

kde4-config --path data

> "/usr/share/apps/umbrello/pics/" the right location 
probably no, see above
> or had to file a bug to chakra's packages maintainers?
yes

Hi, original reporter here.

I have upgraded to the latest version but the crash remains identical (as per description from 2013-01-30) for me.

Running with a virgin KDEHOME or deleting ~/.kde4/share/config/umbrellorc doesn't help.
Running with --export-formats gives me a list (bmp bw dot eps epsf epsi ico jp2 jpeg jpg pcx pic png ppm rgb rgba sgi svg tga tif tiff webp xbm xpm xv) without crashing.

The bug may not be triggered anymore by Giuseppe's setup, but it's still there, unchanged, on my setup. Please tell me if there's any manipulation I can do to give you more information.

> $ umbrello --version
> Qt: 4.8.4
> KDE Development Platform: 4.11.1
> Umbrello UML Modeller: 2.11.1

yes, please try the change mentioned in comment 12

This earlier bug contains also a fix.
