guvcview crashes when capture image (JPG)

[Hung Tran]

This bug happened in Lubuntu 13.04 Beta live session, I was using Vietnamese locale, tried to capture an image from my webcam with guvcview and the app crashed. There was a problem in submitting bug report at that time so I manually file a bug report here, including the crash log.

I'm not n expert on guvcview ;-) but I thought I can give it a go and I've tried to repeat it, set locale to Vietnamese (vi_VN.UTF-8), save an image to a directory with Vietnamese name and file name but guvcview didn't crash.

Hung Tran, could you attach your ~/.guvcviewrc and perhaps default.gpfl as well please?
I couldn't see anything interesting in backtrace from coredump so it would be good if you could install strace and run from a terminal:

strace /usr/bin/guvcview > guvcview_vn_VI.strace 2>&1

and of course attach guvcview_vn_VI.strace file to the bug report.

In terms of the bug report itself, it looked like apport/python3 couldn't set LC_TIME properly.
What exactly you have your locale set to, it's not UTF8 is it? Could you past output of `locale` run from a terminal please?

Hi pawciobiel

This is the result of locale command:

LANG=vi_VN
LANGUAGE=
LC_CTYPE="vi_VN"
LC_NUMERIC="vi_VN"
LC_TIME="vi_VN"
LC_COLLATE="vi_VN"
LC_MONETARY="vi_VN"
LC_MESSAGES="vi_VN"
LC_PAPER="vi_VN"
LC_NAME="vi_VN"
LC_ADDRESS="vi_VN"
LC_TELEPHONE="vi_VN"
LC_MEASUREMENT="vi_VN"
LC_IDENTIFICATION="vi_VN"
LC_ALL=

I also attach the files you asked, but I don't know where default.gpfl is, I tried to search for it but didn't find.

This is guvcviewrc.

Thank you for your time! :)

I experience the same problem. Capturing video works, but capturing image not.

Same here. Capturing video works flawlessly, but clicking on 'Capture image' crashes it.
Ubuntu 12.04.3 LTS

Only crashes if the selected image format is JPG. Doesn't crash if the selected image format is RAW, PNG, or BMP.
