287681 - Firefox crashes after few seconds of mangle.cgi [@ nsPluginTag::RegisterWithCategoryManager ]

Status: VERIFIED DUPLICATE of bug 287690

(Firefox :: General, defect)

Description

[Pavel Penaz]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050325 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050325 Firefox/1.0+

Todays trunk builds crash after few seconds of running the mangle.cgi script
locally. From my observation this crash does not occur because of the invalid
HTML (FF renders the page on which it crashed quite fine) but perhaps because of
the fast page reloads or something like that. Try running mangle.cgi at this
link: http://84.242.65.71/cgi-bin/mangle.cgi but it is possible that you'll need
to run the script locally to cause the crashing.

Some talkback IDs: TB4593169Y, TB4593130E, TB4593103X, TB4593080X, TB4593057Q

Reproducible: Always

Sorry if this is a duplicate but talkback servers are not working. Marking as
depending on bug 264944.

This link reliably crashes my Firefox:
http://84.242.65.71/cgi-bin/remangle.cgi?0x49e81441

Comment 3

[Oliver Klee]

The dependency was the wrong way round. Correcting so that this bug blocks bug
264944 like all the other similar crashes.

[Pavel Penaz]

Thanks for correcting my mistake.
I have spent last hour trying to come up with a working reduced testcase but I
haven't suceeded. The link above works though and FF crashes after meta-refresh.

It has something to do with Java applets. I get the same talkback on this page:
