I got a very similar crashes in mozplugger. After loading debuginfo packages this is what I got:
Core was generated by `mozplugger-helper 0,1,10,0,0,0,0,0 play "$file"'.
Program terminated with signal 11, Segmentation fault.

1605 }
1606 /* On each repeat we re-open the XServer connection, so need to
1607 * close it at end of loop - TODO perhaps we should keep in open
1608 * for all repeats? */
1609 XCloseDisplay(display);
1610 }
1611
1612 exit(0);
1613 }
(gdb) p display
$1 = (Display *) 0x0
(gdb)
It is quite obvious why it crashes although if a 'display' value of NULL here is legitimate is another good question. After a very quick scan through this code I do no see why not. A guard on an XCloseDisplay() call would prevent that from happening.
it should be fixed in mozplugger-1.14.2-1.fc13 which will be available in f13-update-testing soon. Or you can download it from http://koji.fedoraproject.org/koji/buildinfo?buildID=189076 |
