that reminds me; we have had a similar problem with ABRT and LibreOffice, if an in-process JVM is loaded. see for example: https://bugzilla.redhat.com/show_bug.cgi?id=731614#c9 when the in-process JVM is active and some SEGV occurs, the JVM has its own handler to handle it (even though usually it's a crash in LO's C++ code) and that leads to ~10 identical JVM stack frames on the top, regardless of the actual cause of the crash, and those are of course easily wrongly detected as duplicates. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
