           Summary: random crash opening new folder with IMAP
           Product: kmail
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: alistair devzero co uk

Version:           4.1.0 (using KDE 4.1.0)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc (Debian 4.3.1-8) 4.3.1 
OS:                Linux

It's pretty easy to reproduce this one, just use KMail for longer than 5 minutes on an IMAP server. Part of the problem might be that I'm using a server 1 hop from this machine, so it's very responsive. This may trigger race conditions that more remote IMAP servers wouldn't.

Application: KMail (kmail), signal SIGSEGV
