107862 - Browser freezes for a while when loading a news in zdnet

Status: VERIFIED DUPLICATE of bug 58339

(SeaMonkey :: General, defect)

Description

[Nicolás Lichtmaier]

It freezes for so long that I have though twice that it wouldn't recover and
killed it.

I've entered with gdb so that I could take some pictures of Mozilla's frozen body:

The most suspicious thread is this one:

Ops, I forgot to say that I'm using build 2001102910.

Comment 2

[Nicolás Lichtmaier]

Inspecting with gdb the registers of the "open" syscall frame I get that flash
was blocked trying to open "/dev/dsp" (The sound card was in use as I was
listening to an mp3). So this is surely an old bug it has been surely reported
before. Sorry.. =(.
