User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4 Build Identifier: 0.9.0 I've been using Thunar (0.9.0) on Ubuntu (8.04) without problems for a few weeks. I've aways been using the Shortcuts side pane. Today I discovered the Tree side pane and began using that. Within minutes it froze, after I covered part of the Thunar window with my terminal window and then tried to uncover it -- the covered part of the window never refreshed. I had to "force kill" that Thunar. Repeated attempts have yielded similar freezes. Twice my entire Gnome desktop froze and I had to reboot. I googled the internet and have seen others with the same issue (http://ubuntuforums.org/archive/index.php/t-368871.html). I know you folks are putting out a new release soon. I hope this issue is addressed. In the meantime, I'll stop using the Tree side pane. Here's a stack dump after Thunar is frozen: ... lots and lots of threads [New Thread 0xb42efb90 (LWP 25024)] [Thread 0xb42efb90 (LWP 25024) exited] [New Thread 0xb42efb90 (LWP 25025)] [Thread 0xb42efb90 (LWP 25025) exited] [New Thread 0xb42efb90 (LWP 25028)] [Thread 0xb42efb90 (LWP 25028) exited] Program received signal SIGINT, Interrupt.

On my Ubuntu, I have turned on accessibility: System -> Preferences -> Assistive Technologies... click "Enable assistive technologies". 2. Bring up a terminal or two 3. Bring up Thunar 4. In Thunar: view -> sidepane -> Tree Excecute the following steps until Thunar's window does not refresh: 5. expand a branch in the tree or collapse a branch in the tree 6. cover part of the file/folders window with an xterm Actual Results: When I execute step 5 the 2nd or 3rd or 4th ... time, I first click on the Thunar window to bring it to the front. You know you've hit the bug when the window comes to the front, but the part that was covered does not refresh -- it stays blank. Expected Results: The Thunar window should always refresh.
Do you expand folders in the tree with a lot of activity? For example /proc or /dev? What does the cpu usage do?
No. I expand "user" and then for each iteration (steps 5 and 6 in my steps to reproduce) I either expand or collapse a subfolder under "user". Neither folders contain very many entries. In response to your question I used a terminal window running "top" as the window to cover/uncover Thunar. Top showed Thunar itself grabbing 80-90% of the CPU for about 6-9 seconds just before hanging. If I do not cover the Thunar window, then each expand or collapse uses about 3% of the cpu, tops. Note: If I do not cover the Thunar window it behaves fine.
And when assistive technologies is disabled?
Good question. I wish I had thought of it. It still hangs. So my statement that it is accessibility related may be wrong. I reran the gdb session a few times. As before, Thunar works correctly until I cover the tree view with another app (terminal running gdb in this case). One of the back traces, immediately below, looks like it still has accessibility stuff running. Maybe I have to reboot Ubuntu before my settings take effect. I can't do that right now. Here is that back trace, there's another one below. Program received signal SIGINT, Interrupt.
