Cheese crashing

[Anne Wilson]

When I launched cheese on the Acer Aspire One I saw what looked like the 
startup screen, but then it immediately crashed.  I'm wondering whether it is 
a problem of missing driver or something else.  Anyone have any hints?  
Thanks

Cheese is a gnome app as far as I know.

However try to open cheese in terminal to see if it will show any
error messages:
Open the terminal and type in the promt "cheese" and press enter. What
does it say, if it says anything?

Someone had asked about an application to work with webcams, and I was pretty 
sure that I had used cheese to check the Acer Aspire One webcam, when I first 
installed F10.  For myself, I rarely need this, and would be happy to try 
anything else.

Yes, I'd already done that.  Although the symptoms are the same as reported in

the bug link Mary Ellen gave, the error messages aren't, and this is a kde-
fedora-updated F10, not F11.

I thought it was looking for glibc, but

Package glibc-2.9-3.i686 already installed and latest version

I think those are all warnings from glib, and possibly not relevant;
I'd still be tempted to blame the segfault on the same root cause as
the F11 case. What's your version of libv4l?

glibc: standard core C libraries
glib2: low-level library for GTK and GNOME

I think the warnings above are about glib2 issues, not glibc issues,
and glib2 is a dependency (direct or indirect) of all GNOME apps so it
can't be missing.

According to the bug report, the crashing is an issue with
libv4l-0.5.98 and is fixed in 0.5.99. I assume the maintainer will
push the fix to all affected platforms ...

Ah - I didn't spot that.  Thanks.

Hi Anne,

I've never used cheese before and I don't own a AA1, so my feedback  
may not be too useful.

First, I didn't have my webcam plugged in and cheese started up just  
fine and after a couple of seconds it told me that I didn't have a  
camera. Then I tried a camera, for which I don't have a driver  
installed, with the same result as before. When I plugged in a working  
cam, cheese displayed a picture, but I seemed to be unable to take  
snapshots.

Judging from my rather limited experience, I don't think a missing  
driver should crash cheese. A broken driver will be another story,  
though.

Have you tried to use the cam with any other program, for instance  
kopete? I've been using luvcview with good results in the past

I hadn't actually tried it with anything else, but I fired up kopete, which 
instantly told me that I have an Acer Crystal Eye webcam, and produced a 
picture better than I expected considering the lighting condition.
