And looking at the backtrace and the comment about gdb producing garbage backtrace this seems to be simply a broken Qt installation. There's most probably some kind of binary incompatibility. Is this a package, if so I suggest to complain to the package developers. If you've built yourself then remove the installed files, remove your builddirectories and start a new build from scratch. 741135 5 apaku 2009-04-09 20:38:02 +0000 *** Bug 189237 has been marked as a duplicate of this bug. *** 741137 6 apaku 2009-04-09 20:41:14 +0000 Hmm, this seems to happen only with trunk, not with my 4.2 (checkout is pre 4.2.2 iirc)/Qt4.4.
