           Summary: kimg_eps triggers LyX crash
           Product: kdelibs
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kimgio
        AssignedTo: kdelibs-bugs kde org
        ReportedBy: juergen.sp t-online de


Version:           4.0.0 (using KDE 4.0.0)
Installed from:    SuSE RPMs
Compiler:          gcc 4.2.1 
OS:                Linux

We had several reports from LyX users on Linux where LyX crashed on previewing EPS graphics inside the LyX workarea (cf. http://bugzilla.lyx.org/show_bug.cgi?id=4409). The problem occured with several versions of kdelibs4 (up to 4.0) and different distributions (Fedora8, openSuse 10.3).

The backtrace indicates that this problem is triggered by kimg_eps from kdelibs4. All reporters confirmed that uninstalling kdelibs4 fixed the problem. Thus we believe the problem is on the kdelibs side.

Here is a backtrace produced on openSuse 10.3 (x64) with LyX 1.5.4svn (Qt 4.3.3) running in KDE 3.5.8. KDE 4.0 (from the openSuse build service) is installed:
