Description xaphir 2012-04-04 17:28:39 UTC 
Description of problem:

emelfm2 was rock solid up until sometime around January or Febuary; Fedora 16 was released in November iirc. After kernel and other updates around that time, odd things began to occur.  Only recently did I take a hard look at it cause segfaults started happening.

The fault as tested happens when copying or moving files.  It's happened in other instances of use as well, but this was the first reproducable condition I had gdb test results on. 

Version-Release number of selected component (if applicable):

emelfm2-0.8.0-1.fc16.x86_64

How reproducible:

Attempt a file copy or a move, multiple attempts may be required.

  
Actual results:

Segfault

Expected results:

No Segfault

Additional info:


Here is a gdb report as requested by the maintainer:
