Kdevelop sigseg on exit, sigalrm anytime: libc fault?

Question

kdevelop 95% of times crashes on exit. that's kdemod version (which is different only in depending on kdemod-kdesdk). anyone else experiences this?
looking at the backtrace, not the same parts are involved (here it's kate related, but kate itself is rock solid, and sometimes it's other) but the part ALWAYS involved is:
#6 0xb634a6b3 in malloc_consolidate () from /lib/libc.so.6
#7 0xb634c035 in _int_free () from /lib/libc.so.6
#8 0xb634c2a9 in free () from /lib/libc.so.6
here's the gdb backtrace, as given by the crash handler:

this is getting annoying.
