Firefox crash when Appearance Preferences/Theme used

[richbl]

Binary package hint: firefox

Does:
1) Start Firefox application (firefox 2.0.0.8 2nobinonly-0ubuntu1)
2) Open Appearance Preferences dialog
3) Click unselected item in Themes tab
4) Observe Firefox CPU utilization increase, and application hang

Should:
1) User should change appearances without Firefox crash

Notes:
There appears to be several closed/fixed bugs in previous Ubuntu releases that may suggest similar functionality (#35780), and provide additional information.

As this this my first bug filed against Ubuntu, please let me know if there is anything more that I can provide (dumps, traces, etc.).

I do not have this problem.
Does the bug occur when you change a preinstalled Ubuntu theme? Or does it occur only with themes from Gnome-art or websites like it?
Do you have any theme installed on Firefox?
Can you try to reproduce the bug with a new empty profile? (firefox -profilemanager)

On further testing, I see either additional or changed behavior. Unfortunately, during the period when I logged this bug, and what I see now, I installed/uninstalled a number of packages, so my test case may no longer be valid on this machine.

In any case, here's what I'm now seeing:

Does:
1) Start Firefox application (firefox 2.0.0.8 2nobinonly-0ubuntu1)
2) Open Appearance Preferences dialog
3) Click unselected item in Themes tab
4) Observe Firefox CPU utilization increase; application is hung
5) Firefox CPU utilization continues for between 3 - 10 seconds
6) Firefox then redraws (refresh) and the application is once again functional (no "force quit" dialog is issued)

Should:
1) User should change appearances without Firefox "hesitation"

Again, since my machine has undergone some changes since I first logged this bug, I'd be inclined to call this "not repro" and close it out.

However, in my current configuration, I still DO see some unusual behavior, though it most certainly is not an application crash. It appears now to be more likely a GTK issue with updating window styles, of which perhaps Firefox just happens to take some time/horsepower updating.
