Version: (using KDE 4.2.1) Compiler: gcc 4.3.3 OS: Linux Installed from: Compiled From Sources On startup and on manual start (when issuing plasma in terminal) There are no any widgets used except folder view. I recall no changes, except eventual recompilation (without any source changes). Everything worked fine for about a week and now I how no desktop at all. I've seen several similar bug closed reports, but they seem to be not the same, so I decided to post a new one. Sorry if it is duplicate. The important note though: I split kdesupport to separate pieces and using the Qt 4.5 not qt-copy. However this seem not be the trouble since desktop worked fine for about a week.

This is bug 185741, already fixed in KDE4.2.2/4.3 . As a workaround you can modify your plasmarc file (as stated at bug 185741 comment 3 ). In that bug report you also have the svn commit that fixed this crash (if you want to apply it against your sources...) Thanks for reporting *** This bug has been marked as a duplicate of bug 185741 ***
