[Bug 250718] [NEW] FireFox Downloads window "Clean" button causes bizare behaviour

[Bili Joe Campbell]

Public bug reported:

Binary package hint: firefox

With a rather long list of downloads (may not be relevant), clicking the
"clean" button caused close buttons on Firefox main window, and download
window to fail to respond.  Processor (one of two processors shown in
system monitor for a Pentium 4 in hyperthreading mode) was driven to
100% and stayed there.  If the download window, or a console window, or
the system monitor window was moved, it left behind thousands of copies
(like a deck of cards, fanned out), and drove the other processor to
100% (fell back to a lower value when stopped moving window.  Had to use
"Force Misbehaving Application to Quit" feature to close downloads
window--FireFox's main window disappeared at the same time, but FireFox
continued to run (on trying to open FireFox, got the message that
session was already running and must be stopped before opening another.
Used "top" to get pid for FireFox and then used "kill" shell command to
end the invisible FireFox session.  System then appeared to return to
normal operation.  After going through this cycle several times, when I
opened the Downloads window, it was empty, and no longer seemed to cause
strange behavior.

Using Ubuntu 7.10, FireFox version 2.0.0.16

Note: Entire system seems to have been running slower lately.  Not by
much, but I don't think it's just my imagination.

I would like to provide more information, as per your document
"DebuggingProcedures", but since the Downloads window is now empty
(i.e., at some point, the "clean" function did work), I can no longer
reproduce the bug.  If it occurs again, I'll try to supply additional
information
