Could you try to get a complete backtrace? Not running kde, or
enabling/using a core file maybe helps.
Under Gnome it's even a bit worse: after killing gdb and reentering X, the mouse pointer disappears! Hitting Alt-F1 to get a keyboard menu seems to resucitate the pointer.
Anyway, enabling core files doesn't seem to help much, as the lyx.org rpms have no debugging info in them. Sorry, but I don't have time right now to make a debug build and play with it. If I make lyx dump core and try to load the core into gdb, the backtrace is pretty uninformative:
(gdb) core core.18511 Core was generated by `lyx'. Program terminated with signal 6, Aborted. #0 0x42028851 in ?? () (gdb) bt full #0 0x42028851 in ?? () No symbol table info available. #1 0x420284f4 in ?? () No symbol table info available. #2 0x42029beb in ?? () No symbol table info available.
... more of the same (19 stack frames total) ...
Sorry for not being able to work more on this one.
Best,
f.
