I'm on Kubuntu Jaunty fully upgraded at 2009/04/26.

I don't know what is the "connection failure" but it happen as soon as the video start, and it is not related to the crash (or it seems so...).
edit: it may be because I don't use pulseaudio...

I'm on kubuntu jaunty fully upgraded at 2009/04/26.

It may be related to some codec and not to moonlight, but rigth now I don't know how to locate the exact cause.

Before the crash all work properly for some time.

some time it may take an hour to crash, but it will crash...

This site is region-locked to Italians only, which makes verifying and diagnosing it very difficult

[Jo Shields (directhex)]

Are you using the built-in ffmpeg codecs, or the Microsoft codecs? (right-click on the Moonlight control to get the install option). If the former, try the latter. If it doesn't crash with the MS codecs, it's an FFmpeg bug.

[Andrea Bravetti (andreabravetti)]

I'm using ffmpeg rigth now, I will try with the ms codec...

I can setup a proxy for you if you can debug it...

[Andrea Bravetti (andreabravetti)]

Now I'm testing it with the ms codec...

[Andrea Bravetti (andreabravetti)]

it crash in the same way even with the ms codec.

<OT>
and I tainted one of my linux box... should I reinstall it from scratch? No, I'm joking, but how to remove this codec?
removing .mozilla/plugins/moonlight/silverlight-media-pack-linux-x86-5-1.so is enought?

[Jo Shields (directhex)]

Yes, deleting that file is enough.

Can you follow the instructions on https://wiki.ubuntu.com/MozillaTeam/Bugs#Crashes to obtain a backtrace? You'll want the libmoon-dbgsym, moonlight-plugin-core-dbgsym and moonlight-plugin-mozilla-dbgsym packages as well as those named. I can then present the info to upstream, who can help find a fix

[Andrea Bravetti (andreabravetti)]

I followed the istructions at https://wiki.ubuntu.com/MozillaTeam/Bugs#Crashes and gdb showed this:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb7dba6d0 (LWP 7803)]
0xae101b73 in alsa_lib_resampler_process_int () from /usr/lib/alsa-lib/libasound_module_rate_speexrate.so

so, I installed libasound2-plugins-dbgsym and that message become:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb7c6c6d0 (LWP 8219)]
0xadf2ab73 in alsa_lib_resampler_process_int (st=0x9824f80, channel_index=0, in=0xbd0abc58, in_len=0xbf94a830,
    out=0x3c28f927, out_len=0xbf94a828) at resample.c:915
915 resample.c: No such file or directory.
        in resample.c

Attached gdb-firefox1.txt (normal) and gdb-firefox2.txt (with libasound2-plugins-dbgsym).

So, I installed source for libasound2-plugins and the offending line seems to be this:

   for (i=0;i<*out_len;i++)
      out[i*st->out_stride] = WORD2INT(y[i]);

If I'm not wrong the bug should be assigned to libasound2-plugins.

[Andrea Bravetti (andreabravetti)]

I was wrong...
If this time I'm not wrong the bug should be assigned to alsa-plugins (source of libasound2-plugins)....

[Andrea Bravetti (andreabravetti)]

I reported this bug here too:

Can you reproduce this symptom in current lucid?
