when this is reproducible, please run kdevelop through valgrind and show us the log it produces: valgrind --track-origins=yes --num-callers=25 kdevelop
Created attachment 53362 [details] kdevelop valgrind log
I'm trying to enable Joseph Wenninger's HTML autocomplete plugin inside Editor > Settings (I don't know the exact name since I'm using a localized version). Kdevelop crashes every time so this bug is easily reproducible. A small consideration. Even if I understand that working on crashes like this one is very painful IMHO asking the user that experienced a (sporadic) crash to provide a valgrind log is setting the bar a bit too high even if the user is collaborative. It requires a lot of time and memory even when the crash is always reproducible and need only three or four click from the start. My 2 cents.
Duplicate of 238864, which in turn was a duplicate, let me quote Christoph: Closing this as a duplicate of bug 170806 because the backtrace indicates that the XMLGUI client list contains stray pointers. If you are experiencing toolbar or shortcut related crashes again with KDE 4.5.3 or later, please create a new bug report. *** This bug has been marked as a duplicate of bug 170806 *** *** This bug has been marked as a duplicate of bug 170806 ***
Not a duplicate. Bug 238864 had clear references to XMLGUI in its valgrind log, this one does not.
@Milian > If you are experiencing toolbar or shortcut related crashes again with KDE > 4.5.3 or later, please create a new bug report. I'm on KDE 4.5.3
I cannot reproduce nor find out how that could be anything different than bug 238864... Esp. since it's the very same backtrace and the valgrind log shows some invalid Actions or similar... Anyone got an idea what to do here? /me doubts it's anything in KDevelop
dfaure looked at the valgrind, says it's a duplicate of 249884 but with a different origin. He has it on his todo to fix it properly upstream in Qt. Btw., you said: I'm trying to enable Joseph Wenninger's HTML autocomplete plugin inside Editor > Settings (I don't know the exact name since I'm using a localized version). Kdevelop crashes every time so this bug is easily reproducible. This reminds me that I changed the location of the config action to be in settings and always visible, this should fix it for KDevelop 4.2 onwards.
