Bug 203590

- Can you post the backtrace of the crash ? (using the "Developer Information" tab of the crash handler dialog) You may need to install the "kdepim-dbg" package in order to get a better backtrace. Thanks

I just made an upgrage (aptitude safe-upgrade) and now is worst... now kmail crashes as soon as I press save attachment. Here is the trace:

Thank you for your report. Kmail1 is currently unmaintained and the code has changed sufficiently in Kmail2 so the backtraces are not really useful anymore. Should you experience the same crash in Kmail 4.8.5 or later, please open a new report for Kmail2. Thank you for your understanding
