Comment 1 Andreas Pakulat 2010-02-23 23:36:55 UTC 
Please install debug symbols for kdevelop, the backtrace is not very useful. (KDirWatch problems are supposed to be fixed in kde 4.4.0 afaik).
Comment 2 Milian Wolff 2010-02-23 23:40:22 UTC 
no, 4.4.0 is crashy but should be fixed in 4.4.1 according to David Faure.
