Description gertvv 2004-02-19 16:00:52 UTC 
When playing back from a samba source, the input sometimes mysteriously hangs..


Steps to reproduce:
1) play back a lot of mp3 files via gnomevfs smb
2) wait until playback stops (even though there are still files queued)


This is very unpredictable, sometimes it will hang on the first file played
back, sometimes it will take 20 or even more songs. Stopping and starting
playback (even on a different file) has no effect: from this point onward,
no file will play, until the executable is restarted.

I have tried to produce a backtrace, by interrupting execution when
playback hangs. Playback is done in a separate thread. Here are the backtraces:

Accidentally clicked 'submit'. Sorry. Backtraces:

The same thing also happens with input from local files, so it's not a
samba related bug. The backtrace is the same.

Worth noting:
A new thread IS created in order to start playback, and (judging from
samba debug output - which is quite verbose :P) a first portion of the
file is read, but playback never starts.

May have had to do with me re-using spider. Maybe you should note
something about spider not being re-usable somewhere in the
application development manual? (see #134851)

I'm trying to reproduce this bug with correct use of spider, I'll post
another comment here when I know more.

Does this happen with 0.8.0 as well?  (probably)

Could you use "thr a a bt" (short for "thread apply all backtrace") to get the
backtrace?

Gert, have you been able to reproduce this issue with correct use of spider?
I'll add a comment in the appdevman, but would like to close this bug if it's
unreprodueceable.

Nothing heard back on bug closing. Please re-open this bug or open a new one if
this is still a problem.
