KMail is still failing for me, but Backtrace has started reporting stuff, as follows: (no debugging symbols found)...(no debugging symbols found)...

Anybody interpret what's wrong, here? Or, is there a HowTo or a website that can tell me how to interpret the above output? Meanwhile, I have done the following: - created another user on my system -- KMail starts for that user, but of course does nothing because the user doesn't have a mail account on our company server... still, the program starts with no reported error - moved my own /home/kmclauchlan/Mail directory and it's subdirectories to a temp directory - tried starting KMail again -- no change - copied the virgin, empty /Mail directory structure from the "Otherguy" user into my home directory started KMail and it failed as usual with SIGSEGV before opening Previously, I had reported re-installing the knetwork package, which is purported to contain KMail. That had no effect. I'm baffled as to where to look. Why would ONE program be segfaulting? How do you trace to see what it wants, that it's not getting? I didn't see any log files in /var/log that seemed to be KDE-related. Does anybody know a good HowTo on "debugging Kommercial apps for Dummies" ?? Is anybody using directories with KMail, rather than MBOX? I was told, last year that this was preferable due to the server I'm connected to. I don't recall the reasoning. /kevin (now with 2520 messages in his Outlook inbox cuz he won't let Outlook "delete viewed messages from server" before he can get Linux mail working again... Mygawd it's ugly! :-)
