--- Comment #24 from Till Schäfer <till2.schaefer at uni-dortmund.de> ---
same here on gentoo with kde 4.12.2

i guess this is a kmail problem, because kmail shows the same symptoms on my
system. 

i opened a gentoo bug before: https://bugs.gentoo.org/show_bug.cgi?id=498066

~ $ kmail --nofork

------

the last two lines are printed after quit. but nothing special pops up. is
there a way to get more information?

this bug only affects one off my two machines. however i cant tell the
difference. 

--------
