Version: 1.5.4 (using KDE KDE 3.1.4) Installed from: Debian testing/unstable Packages OS: Linux KMail has crashed on numerous occasions over the past month. Same behaviour each time. SIGABRT crash, backtrace is to KMime::Codec:decode in libkdenetwork.so It may be misdirection, though. I have three mail filters routing to the same folder and this is the folder which seems to cause the problems. It may well be a thread/locking issue. Going to the folder would reliably SIGABRT. Deleting the indexes and restarting the application didn't help. Removing all messages from the folder and restarting did fix the problem. When I tried to copy in some of the old messages and restarting, KMail crashed again. I had to clear out the folder and delete the indexes for it to restart properly.
SIGABRT are generally caused by failed assertions. If that is so, the program prints the faulty line number and assertion to the output. Can you find that for us?
