Status changed to 'Confirmed' because the bug affects multiple users.

[karl anliot (kanliot)]

bug is very vague. almost worse than useless because devs need to duplicate the setup to reproduce

[Phill Whiteside (phillw)]

I had marked this as incomplete as per comment. #6 But there is full apport trace. If there is not enough information on an apport trace, then the person who maintains the program should include more apport triggers. Whilst that happens, the person who filed it as a full apport report should be asked, politely, for more information and not be told "it is vague". response #6 is not helpful to anyone.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

[yamo (stephane-gregoire)]

Drag and drop a directory to a directory named D and then open D.

[karl anliot (kanliot)]

I need more info. Please assume I can't reproduce the bug.

The problem at gtk/fm-folder-view.c:456 (see comment #2) has been fixed in pcmanfm git repository so this bug should be fixed as soon these changes come into ubuntu package.

1) detailed bug reproduction info is provided at Debain BTS;
2) it has been fixed in LibFM 1.0: http://blog.lxde.org/?p=939

3) as for now, Ubuntu Quantal has libfm 1.0.1-0ubuntu1, so I'm marking it as "Fix Released" (IMHO, at least a patch should be applied at Ubuntu Precise pacakge version).
