Very little to go on without a usefull backtrace. It could be a dupe of bug #57902. Could you please try without the "History" plugin (settings -> plugins) loaded and report back?
If the history plugin is disabled, it doesn't crash anymore. But it crashes when a file is open and I disable the plugin with a SIGSEGV and this backtrace. 0x2965b900 in __sys_poll () from /usr/lib/libc_r.so.4 #0 0x2965b900 in __sys_poll () from /usr/lib/libc_r.so.4 #1 0x2965ae4c in _thread_kern_sched_state_unlock () from /usr/lib/libc_r.so.4 #2 0x2965a811 in _thread_kern_scheduler () from /usr/lib/libc_r.so.4 #3 0x0 in ?? () If I disable the plugin with no file open, then everything works fine.
Ok, then it is most likely a dupe. Closing as such. The history part is on my todo list.. *** This bug has been marked as a duplicate of 57902 ***

Thanks, very nice and readable backtrace. More so than the previous, but.. It would be better if you posted to the open version of this report (bug #57902) and also, if you added some info about your system. Currently, I only know of this happening on Solaris and FreeBSD. The KDevelop code is not different for these platforms, but the underlying libs might well be. So far my best theory is that we're hitting differences in Qt with this one. Either way, the current History plugin should go away, the best workaround for now is to simply disable it.
