           Summary: Crash when selecting "Watch article" while article list
                    being updated
           Product: knode
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: knode-devel at kde.org
        ReportedBy: psychonaut at nothingisreal.com


Version:            (using KDE KDE 3.1.4)
Installed from:    SuSE RPMs

KNode crashed for me today; here's what I was doing at the time:

Click on a newsgroup in the left-hand pane.  KNode starts fetching new article headers from the server.  Meanwhile, I right-click on one of the newsgroup's articles in the header pane and select the "Watch this article" command.  KNode crashes with a SIGSEV.

This has never happened before, and so far I haven't been able to reproduce the problem.  Here is the backtrace data:
