Package: firefox
Version: 1.5.dfsg+1.5.0.1-4
Severity: normal
I was attempting to reproduce a bug I just saw for the first time
regarding rearranging tabs by dragging them, but wanted to start with
a fresh process, so I ssh -X'ed to a different machine, and ran
firefox -no-remote, which started a new process, as expected. I
created a new tab with ^T, and then attempted to rearrange the 2 tabs.
This left me with the "you're in the processes of doing a drag
operation that won't succeed if you stop dragging now" cursor, but the
other machine has tabextensions installed, so I figured that it might
just act differently, and stopped dragging. This seems to have frozen
the FF process, and I was unable to interact with the X server until
killing the remote FF process at a VT, because the cursor was still
being held by FF, I guess.
As it turns out, this is not resolved by removing tabextenions, and I
can reproduce it on a different machine.
It seems to get stuck reading from a pipe, which is nearly always
returning EAGAIN. Perhaps this is just extra slow, but it really
seems to be stuck, and it is really bad that it makes the xserver
unusable..
