           Summary: Infinite loop on Find
           Product: kdevelop
           Version: CVS
          Platform: RedHat RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: jonsmirl at yahoo.com


Version:           CVS (using KDE KDE 3.1)
Installed from:    RedHat RPMs

I entered a find string in the dialog and infinite looped. As far as I could tell there was nothing unusual about my search. Just a fixed string of alpha characters.

I broke into the loop with the debugger, but I didn't have source for all the libs on the machine. It looked like KoFind was looping calling QString:find.
