Can you reproduce the crash all the time ? Does it happen with certain colors or with everyone ?
Thanks

Reproducable and with every color.

I tested an other plasmoid (digital clock) an it works.

Install the "kdelibs5-debuginfo]", "kdebase4-workspace-debuginfo" and "kdeplasma-addons-debuginfo" packages (or if you were compiling KDE4 from source, recompile it with debug symbols enabled) and paste here a complete backtrace.

Thanks

Sorry, I can't find the SuSE debuginfo-packages for KDE 4.3.61. You have an idea where can I get the these?

I encountered this bug using KDE 4.3.00 (ubuntu packages)

@Jeffrey: can you reproduce the crash at will? can you get a backtrace from the crash? Thanks

Yes, it happen when i press 'OK' after changing fontcolor.

The line of the crash is:

QList<QAction *> colorActions = m_colorMenu->actions();
-> QString tmpColor = colorActions[ui.notesColorComboBox->currentIndex()]->property("color").toString();

So it is accessing an invalid index in colorActions.

I can't reproduce here on 4.4trunk

- Is this still crashing on KDE 4.3.1 / and updated trunk ?
- Do you use the standard Plasma theme? (Air or Oxygen), or some other theme ?

Thanks

Same problem here on Kubuntu 9.04 32 bit with KDE 4.3 from kubuntu's repos.
Very annoing problem!

Experinced same problem, 64-bit kubuntu 9.04 + kde 4.3.2 from ppa repos. For me, reason seemd to be some custom theme I had installed (i think it was glassified or oxyglass). Notes widget started up totally transparent and changing colors crashed plasma. 
When I opened my desktop-settings, "theme" dropdown had empty value selected and so was notes-widget's color dropdown. 
Changing to Oxygen theme solved problem. So for me, it was broken(?) theme that caused problems.

- Can anyone else confirm comment 12 ? Thanks

I can confirm comment 12: tested with:
 - Air: crash
 - Oxygen: do not crash

Does this still happen with kde in trunk? i really can't reproduce this with 4.4

i'm closing this for now because i can't reproduce it with trunk (4.4). please reopen if somebody can (for example with 4.4 beta 1)

Reporter of bug 225856 is experiencing this on KDE SC 4.4RC3
- Information about the crash:
I have the newsfeed widget in a left colomn and the note widget in the right
column of the newspaper activity. Since it is impossible to tell where the
bottom of the note widget is (there is no "square" around the widget) I wanted
to change its color. Unfortunately plasma-netbook alwyas crashes when I hit OK
in the settings dialogue.

ok confirmed, in kde4.4 doesn't crash
