Comment 1 Thomas Moschny 2012-05-14 10:28:35 CEST

Can you please try guvcview-1.5.3-1.fc16 from testing and see whether it still crashes?

Done, yes it still does.
Attaching new ABRT trace/report.

Sorry for the "ABRT appends", reuploading.

Btw, trace event log keep reporting 4 missing debuginfo packages (see event log).

Here by default I only enable official Fedora repos, any other on-demand only.
So I installed manually the following

# yum UPTDBGFUSF in guvcview-debuginfo

and now get 

# yum lsi guvcview* | grep guvc
guvcview.x86_64           1.5.3-1.fc16 @rpmfusion-free-updates-testing          
guvcview-debuginfo.x86_64 1.5.3-1.fc16 @rpmfusion-free-updates-testing-debuginfo

but re-running the trace still report the 4 same packages as missing.

Comment 4 Thomas Moschny 2012-05-14 19:47:07 CEST

The trace itself is missing.

Regarding the 4 missing build-ids, do you have some extra packages installed?

What does "yum list extras" show?

Oops, ¿what, how? ..indeed.
I should have carefully checked myself, I will accept a blame :)

( FWIW, went through ABRT wizard _again_ where backtrace *is* still accessible, both from its own tab and "click to edit" row on last screen, but hey! nope, "logger" reporter loose it between "now and then" - not included in the created log file. "Oh well", copy/paste always works :)

Anything else missing in there, that could help ?

Sure, quite a few on this system (with much care, thou).

Like I write, I build the webcam .ko for each kernel.
Could the missing ones be his ?

Comment 7 Xavier Hourcade 2012-05-15 03:18:23 CEST

( fyi cf. ABRT, reported https://bugzilla.redhat.com/show_bug.cgi?id=821576 )

Another blame for me, I must be blind :)

Could these decoding/format libs be implicated in such type of (GIU?) crash ?

So, from my trace I identified these atrpms (whose debuginfo repo wasn't set)
  libavcodec53-0.10.2-54.fc16.x86_64
  libavutil51-0.10.2-54.fc16.x86_64
  libx264_118-0.118-17_20111111.2245.fc16.x86_64
  libxavs1-0.1.51-2.fc16.x86_64

and assume they are matched by these:
  fmpeg-debuginfo-0.10.2-54.fc16.x86_64
  x264-debuginfo-0.118-17_20111111.2245.fc16.x86_64
  xavs-debuginfo-0.1.51-2.fc16.x86_64

Defined the repo, did (yum) install xavs ok, but others failed (deps issues).
Attempted to regenerate the trace in ABRT, which succeeded ...the opposite :D
It auto-installed them all, but now points libxavs.so.1 as the last missing (?)

Attached is the resulting trace, looks similar enough :)

Comment 9 Emmanuel Seyman 2013-02-12 01:41:58 CET

This version of Fedora will reach end of life today (2013-02-12) and RPMFusion will no longer be releasing updates for it. This bug will be set to RESOLVED:EXPIRED next week to reflect this.

If the problem persists after upgrading to the latest version of Fedora, please
update the version field of this bug (and re-open it if it has been closed).

Comment 10 Emmanuel Seyman 2013-02-19 03:29:57 CET

Setting to RESOLVED:EXPIRED since RPMFusion is no longer releasing updates for
this version of Fedora.
