These STR were fixed by bug 578711, but the underlying crash/failure still
remains as bug 579346.

Since this bug has a crash, but not a stack sadly, we'll dupe to this one.

New STR:
 0. Configure Fennec with a Weave account
 1. Enter "about:sync-tab"
 2. After that page loads, open a new tab.
 3. Repeat step 1
 4. Crash

Should be "about:sync-tabs"

Attachment: Backtrace

I see the attached backtrace from the content process on desktop linux fennec.

Comment 5

[Josh Matthews [:jdm]]

I also see the a bunch of errors like the following:

###!!! ASSERTION: must be a file:// url: 'Error', file /home/t_mattjo/src/firefox/mobilebase/netwerk/base/src/nsURLHelper.cpp, line 200

Comment 6

[Josh Matthews [:jdm]]

Actually I believe this backtrace is for a completely different crash for which I have filed bug 583487.

Comment 7

[Josh Matthews [:jdm]]

I cannot reproduce a crash on desktop fennec on linux, but the errors in comment 5 are still reproducible.

Comment 9

[Tony Chung [:tchung]]

I'm not experiencing a freeze when doing steps 1-3 in comment 0.   This happens when starting up fennec from scratch, and clicking tabs from other computers as the first step.  

Its so bad, i need to hard boot my device.   :(

not => now

Comment 11

[Josh Matthews [:jdm]]

The steps in comment 0 are guaranteed to fail right now until bug 583777 is fixed.

Comment 12

[Josh Matthews [:jdm]]

Marking this WFM unless I hear otherwise.

Comment 13

[Josh Matthews [:jdm]]

Nevermind, Tony tells me that this is still a freeze on devices.

Comment 14

[Doug Turner (:dougt)]

freezes or crashes?

Comment 15

[Tony Chung [:tchung]]

If aakash can reproduce the crash, we should keep this bug open.  my situation freezes with the steps in comment 0, but thats not the original bug here.


i'll be happy to file another bug if that clarifies things.
