           Summary: Regression in rev. 1115803, SIGSEGV or SIGABRT in
                    image filters in editor.
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: mbc at baekhoej.dk


Version:           SVN revision 1115803 (using Devel)
Compiler:          gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1 
OS:                Linux
Installed from:    Compiled sources

In many image filters in the image editor, I now get crashes every time I open
them.

I have isolated the bug to between revision 1115803 and 1115800.
The comment for this commit was "Port threaded filters to be a DynamicThread.
Mostly simple find-and-replace work." by mwieswig.

1115803 crashes consistently, 1115800 works without problems. I think there is
a problem with some object being deleted too early. I have observed "d"
pointers becoming zero, but also other behavior.

I will attach a file with stack trace samples.

This is a blocking bug for me that stops me from using digikam SVN later than
1115803.
