Version: (using KDE 4.3.0) OS: Linux Installed from: Debian testing/unstable Packages The microblogging (twitter) plasmoid makes Plasma crash with a segmentation fault. The problem is reproducible using plasmoidviewer as well.
gdb traps the fault here: QGridLayoutRowData::distributeMultiCells (this=0x9d14a8) at graphicsview/qgridlayoutengine.cpp:170 170 graphicsview/qgridlayoutengine.cpp: No such file or directory. in graphicsview/qgridlayoutengine.cpp I'll try to attach a backtrace, although it's very long.
@Giuseppe: don't attach the backtrace, paste into a comment. Thanks
The trace is _very_ long so I'm only pasting the first 100 frames or so. Apparently, the widget gets stuck in a loop trying to resize between two different sizes (maybe due to the scrollbar being created/deleted/created/deleted/etc).

Same problem here. Version: KDE 4.3.0 OS: Linux Installed from: Gentoo standard portage tree
same here, with several plasmoids (microblogging, opendesktop, ecc...) KDE 4.3.0 Linux Gentoo ~ portage tree

Also seeing this with an applet I'm developing that uses Plasma::ScrollWidget. I believe it to be a related problem, since if I remove the ScrollWidget everything is fine and I cannot reproduce the crash. The problem occurs when resizing a Plasma::ScrollWidget. I get one or two lines output on the console like the following QGraphicsGridLayout::itemAt: invalid index 1 QGraphicsGridLayout::itemAt: invalid index 2 When the bug triggers it dumps hundreds of the lines above all at once and the applet crashes with SIGSEGV.
Bug confirmed here. Trying to get top of stack with gdb now (about 13500 frames).
Crash still present in KDE 4.3.3 and Qt 4.5.3. Was using Ubuntu before, now Gentoo. Also, this is the same as 202520.
Crash still there with KDE 4.3.4 and Qt-4.6.0. Gentoo here as well.
In the same situation (kde 4.3.4, qt 4.6.0, gentoo) on two machines (32 and 64 bit) plasmoids works just fine; have you recompiled dev-python/PyQt4 after the installation of newer qt?
Problem still present, but with another user everything is fine. After some testing, it seems the crash only occur when I use the bespin theme Version: KDE 4.3.4, Qt 4.5.3 OS: Linux Installed from: Gentoo standard portage tree
Confirmed that crash only occurs with the bespin theme.
- Are you all using the Bespin widget theme ? If that is the case this should be redirected to its author..
Like jhart, I'm also developing a plasmoid which uses Plasma::ScrollWidget. However, I've seen that the real problem in fact is when using the "Preferred" size policy. I've removed the "Preferred" size policy code and switched it to a Minimum/Maximum approach, and now the plasmoid doesn't crash anymore. It is important to notice that I'm not using the Bespin widget theme, specs below: KDE(support/libs/pimlibs/base) version: trunk (r1062418) - Ubuntu 9.10 Using "QtCurve" widget style / "Oxygen" window decoration
*** This bug has been confirmed by popular vote. ***
@Bruno: could you try to use the Oxygen widget style and check if Plasma also crashes ? Thanks
Hi Dario, I've switched the widget style to 'Oxygen' and now both the plasmoid I'm developing and microblogging are working properly.
Mh... then it could be a problem of QtCurve/Bespin + Preferred sizehint Thanks for checking

Created attachment 39071 [details] Plasma::ScrollWidget segfault fix This is a proposed patch which fixes the segfault when using scrollWidget under certain circumstances (i.e. using "preferred" as unique size policy).
could you try to push this patch into plasma asap? beta 2 is tagged tomorrow. (i don't know it the patch is correct, but try to get into contact with the right people). try to go into the plasma irc channel or the plasma devel mailing list. thank you
