Description Paul Hoepfner-Homme 2003-03-27 18:17:53 UTC 
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:

Hmmm .. can anybody confirm this? I'm unable to reproduce it (cvs.kde.org is too fast? 
;). Anyway I don't see any reference to gideon's code here (only Qt/KDE related), nor I 
see any reference to KDialog* or QButton in current CVS code ... :/

Fixed in CVS, now you can use the stop button to cancel the command, no more need for the 
process dialog.
