Strange crash in kAction::initPrivate

[Andreas Zehender]

Hi!

I go a bug report (#54594) that KPovModeler crashes on startup. I searched the 
message archive and found a similar crash report for noatun and kaboodle 
(http://lists.kde.org/?l=kde-devel&m=103653854417393&w=2)

I don't think that the program is buggy, there are only some simple new calls 
until the program crashes. AND: If I preview a kpm scene in the konqueror, 
the part loads correctly. Maybe the problem is already known or you have an 
idea.

I have two users that have this problem, one of them solved the crash by 
linking the whole program into the executeable and not using the part lib.

The users system:
Debian "testing", 2.4.19 
KDE 3.1.0, compiled fron sources
Qt 3.1.1
gcc 3.21

Here is the backtrace:

After recompiling qt with debug information, he got this useless backtrace:

gdb kpovmodeler
gdb: Symbol `emacs_ctlx_keymap' has different size in shared object, consider
re-linking
