Version:           1.9.50 (using 4.00.80 (KDE 4.0.80 >= 20080104), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.22-gentoo-r9

Today I used Kontact in IMAP mode. When I clicked on a folder and then clicked on the inbox, Kontact crashed. Regrettably I cannot reproduce this crash.
