Oh nice :

Digikam::DatabaseCoreBackend::setDatabaseErrorHandler (this=0x0,
handler=0x14db760) at
/build/buildd/digikam2-2.1.1/core/libs/database/databasecorebackend.cpp:1624

==> this=0x0

Jose :

Look in the trace : 

#5  0x00007f8fcffb556c in ?? () from /usr/lib/nvidia-current/libGL.so.1

digiKam is not relvant of opengl ? You use a NVIDIA video card. Why i can see this trace in crash ?

Can you check if digiKam work fine in another coputer which don't use NVIDIA ?

2.1.1 is built from the 2.1.0 tag? Or any later revision?
Weird: line 1624 is end-of-file then.

Marcel,

yes, Nicolas has used 2.1.0 tag to build tarball.

I CC Nicolas for details.

Yes I use a Nvidia card with drivers propietary

I have what appears to be the same problem on Ubuntu 11.04 x86_64 with Intel graphics.  Installed a couple of days ago from philip5 ppa. Worked well until updated to 2.1.1 last night.  Now segfaults every time.  Backtrace below.

Please compare bug 281767 Comment #13 :(

Can someone start digikam under gdb and compare if the same backtrace results? Line 1624 is the last line of the file, the '}' closing the namespace, so the backtrace is somehow broken.

See http://www.digikam.org/drupal/contrib how to run digikam under gdb. Even better, with current git.

OS: ArchLinux
Qt: 4.7.4
KDE: 4.7.1
Intel video drivers

It seems I have the same bug -- both 2.1.1 and 2.2.0 digikam crash at the startup in Digikam::DatabaseCoreBackend::setDatabaseErrorHandler() (sorry, no debug symbols at hand to provide stacktrace).
If that helps -- I started using digikam directly from 2.1.0. Downgrading to 2.1.0 helps -- digikam starts normally and my photo db seems to be ok.

It seems, my problem was in incompatible config/digikamrc file.
Somehow, when I started using digikam 2.1.0, it created a file with [Database Settings] section, where there were two sets of database options: Images XXX=... and Thumbnails XXX=...
I figured out that digikam 2.1.1+ expects options named like Database XXX=... instead.

So, essentially, digikam 2.1.1+ failed to read my 2.1.0 db config properly -- and in the debug I see DatabaseParameters contains default empty values that causes crash somewhere later in setErrorHandler(), because this=0.

I hope now you can reproduce that. It would be nice to gracefully handle missing/wrong db parameters situation.

Alexey: can you attach such a broken config file?

*** Bug 283480 has been marked as a duplicate of this bug. ***

Created attachment 64322 [details]
digikamrc config from 2.1.0 that causes 2.1.1+ crash

My original config file was already fixed, so I had to reproduce: deleted current config, downgraded to 2.1.0, completed initial wizard, exited, backed up digikamrc, upgraded back to 2.2.0 -> it crashes.

Created attachment 64421 [details]

digikam (2.2.0) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

- What I was doing when the application crashed:

Trying to open digikam 2.2.0 and i can't do it, tried also deleting digikam.db but it didn't help

Removing $HOME/.kde/share/apps/digikam and $HOME/.kde/share/config/digikamrc solves the issue for me

I tried any combinations with current git (only "Database" only "Images/Thumbnails", both) but it just worked and did not crash.
Can someone confirm it's indeed the [Database Settings] section causing trouble?
Or was something fixed in the meantime?

digiKam 2.2.0 is out since few weeks. Crash still valid with this version ?

> digiKam 2.2.0 is out since few weeks. Crash still valid with this version ?
2.2.0 crashes for me, see comments #11, #12, #15.
Don't know if the trunk version crashes.

Alexey,

It still valid with digiKam 2.4 ?

Gilles Caulier

@Gilles
I'm not able to test -- compilation of 2.4.x and 2.5.0 fails, because my system runs boost 1.48 and I'm affected by https://bugs.kde.org/show_bug.cgi?id=287772

Ok, so with the patches from my repo I was able to compile 2.5.0 and test this bug.
When I use digikamrc from the attachment, digikam doesn't crash, it shows the dialogbox 'Error while opening the database. digiKam will try to automatically reconnect to the database' with progress bar which goes on forever. On the console the following is being written:

digikam(25501)/digikam (core): Please set parameters before setting a database error handler 
QSqlDatabase:  driver not loaded
QSqlDatabase: available drivers: QSQLITE QSQLITE3 QMYSQL3 QMYSQL QODBC3 QODBC QPSQL7 QPSQL
digikam(25501)/digikam (core): Error while opening the database. Error details [ QSqlError(-1, "Driver not loaded", "Driver not loaded") ] 

The last line is being repeated multiple time.

If 'Cancel' is pressed in the dialog box, there's an error box about no working database. When I press OK, the digikam crashes:

Thread 1 (Thread 0x7f705d36c980 (LWP 25501)):

#13 0x000000000048d375 in _start ()

Overall, it's better than it was before as digikam reports the source of the problem, but maybe more graceful handling of incorrect data in .ini file is still required.

Official digiKam 2.6.0 release is out since few days now :

http://www.digikam.org/drupal/node/656

Please, check if this entry still valid, or update report accordingly.

Thanks in advance.

New digiKam 4.11.0 is available :

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?

Gilles caulier

I have no issues like this with the recent digikam versions  for quite a while. I don't know, though, whether that's because the potential crash was fixed or digikamrc was always in sync with the recent digikam.
