xx ZBar crashes Firefox
« Thread started on: Sep 24th, 2015, 12:31pm »

Hi

since the latest versions of FF (39,40, ....) I have crashes of FF when my PC hibernates. When re-login after a pause, sometimes the "Mozilla Crash report" tells me that FF is dead. The crash reports say that solhook12.dll makes the problem.

https://crash-stats.mozilla.com/report/index/bp-bfbd51ce-6588-486a-8025-577cd2150924

I'm using Zbar 0.86, 13th Aug. 2014

Cool crash report system - it even links directly to the point in the source code which generated the crash!

However, unless I'm reading it incorrectly, I don't see that it's solhook12.dll which is causing the issue. Yes, that DLL will be part of the FF process (it gets injected into every process when the hook is installed) so that's normal, but why do you think it's ZBar which causes the issue?

Good morning Tom

I posted it to the German Firefox-Forum
http://www.camp-firefox.de/forum/viewtopic.php?f=1&t=114750

and one poster wrote:
"Do you use ZBar? The Crash-report says that FF hangs on solhook.dll"

Well I'll be the first to admit that I don't understand the crash report! Perhaps Boerse Feger does know what all that data means, and perhaps the fact that it's at the top of that list is what points towards it being ZBar.

The obvious thing to try though is to close ZBar, and see whether the problem still happens. When you close the app, there's nothing left behind - although there are some settings in the registry, that's all.

Can you try that? Also, when the FF crash happens, is ZBar OK? Does the problem affect ZBar at the same time?

ZBar is OK after the crash, that's right.

But it is nearly impossible to reproduce the issue - it seem to be a little bit of random-error (once every 10 days ..). And to wait if the PC locks itself and to reactivate .... - no idea to reproduce.

For me, I can live with it. It's not a hard error ....

Have a fine time!
