Can you try a release build ?
The symbols are missing ....

Comment 2

[Wayne Mery (:wsmwk)]

trying v3.5.2 but so far no crash.  (but it's also a clean profile)

comment 0 crash was a nightly exe build which should have had symbols :(

Comment 3

[Arie Paap [:wildmyron]]

I reproduced with that testcase on 3.6a1, required a fair bit of mousing about but similar to comment 0. Also reproduced with recent Namoroka nightly but useless stack (same as above)

wildmyron, can you still reproduce?

> wildmyron, can you still reproduce?

Sorry I haven't taken time to test this until now, I haven't been actively testing Firefox for some time.

I tested this with Win Vista.

- Using same build as comment 3 I could still reproduce with STR from comment 0.

- Using current nightly of 25.0a1, ID 20130804030207, I am unable to reproduce after some time of similar mouse activity.

Not sure how to resolve this bug though.

Thanks Arie. We use WORKSFORME when we don't precisely know what solved the problem
