totem hangs when source does not respond

[Vern Wall]

Binary package hint: totem

When an internet radio station does not respond to a request, totem may or may not time out. If it does not time out, the program hangs. A forced quit may or may not clear the program. If not, I have to reboot the computer to start the program again.

Note: In this case the program said, "An error occurred. You may not have permission to access the source." I pressed Play and totem reconnected to the radio station.

I can confirm this problem that Totem hangs when the server does not respond (so it is probably difficult to reproduce). I have not encountered any problems killing Totem in this situation., though.

In my case, I first opened a webradio station through Firefox, by going to http://www.slayradio.org/home.php and clicking on the "Broadband" link in upper left corner. After confirming to open the file in "Video Player", Totem opened but then didn't react (clock cursor appeared, and the Totem window was not repainted any more).

Looking at ps -Af , I saw that Totem was started with /tmp/listen.m3u as parameter. I killed the hanging Totem instance and started it manually with that parameter; again it didn't respond. However, after a while it timed out and displayed the same message as described by Vern ("An error occured" etc). I clicked OK and then selected another URL from the playlist window, which was then played without problems.

The listen.m3u which is the playlist that was returned from the website contains five different HTTP urls (http://relay?.slayradio.org:8000/), and apparently the very first of these did not respond. I checked this manually on another machine with xmms; it didn't get a connection either to this particular server (relay3), but displayed a meaningful status message ("Connected: waiting for reply").

Looking at the hanging instance with strace -p showed that it waited in a select call:
select(20, [19], NULL, NULL, {26, 612000})

In my opinion Totem should in this case:
- still respond to user interaction
- allow the user to select another entry from the playlist (which should abort the current connection try)
- show a status message that tells the user what's going on (so he knows the app is not crashed, but the server "has a problem")

[Oliver Gerlich (ogerlich)]

Forgot something - this was in the terminal where I launched Totem manually:

** Message: Error: Could not open resource for reading.
gstgnomevfssrc.c(863): gst_gnome_vfs_src_start (): /play/source:
Could not open vfs file "http://relay3.slayradio.org:8000/" for reading: Timeout reached (46)

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Thanks in advance.

[Vern Wall (vernwall)]

Yes, the program still hangs occasionally at random
times. Other times it gives the "Error reading source"
message. This happens about once a day.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Hardy Heron. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu. You can find out more about the development release at http://www.ubuntu.com/testing/ . Thanks again and we appreciate your help.
