envp=<value optimized out>) at ../../kinit/kinit.cpp:1841 Reported using DrKonqi 918883 1 adjam7 2010-02-17 10:25:50 +0000 Quite annoying, yes.. My commit a2ad510 should fix this. Please, test again with today's rekonq code. I'll wait your confirm to close this. (btw, thanks for your report and the backtrace) 918920 2 mikael.gerdin 2010-02-17 11:14:08 +0000 I manually cherry-picked commit a2ad510 and appied it onto 0.3.90 and built in on my launchpad PPA. So far so good, but as I said I could not reliably reproduce it. Considering what it crashed on and the fix for it I'm just set it to resolved and reopen it if it appears again.
