           Summary: KDevelop crashes when user cancels a CVS diff command
           Product: kdevelop
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: zcu2k001 at sneakemail.com


Version:           unknown (using KDE 3.1.0)
Installed from:    Gentoo
Compiler:          gcc version 2.95.3 20010315 (release)
OS:          Linux (i686) release 2.4.19-pre7

If I run CVS diff on a file I've modified, it sometimes takes a very long time for the CVS diff command to complete due to network congestion. In some cases I wish to cancel the command and try later. However, if I press Cancel in the window that pops up saying it's waiting for CVS diff to complete, KDevelop crashes. Here is the debug backtrace:
