acostach commented 9 years ago

Hi, I'me receiving some stack traces from a machine that's not in my possesion for a bug which I cannot reproduce.

The version used is 0.4.0. The tester reproducing the crash cannot check with latest version unfortunately as it's a controlled setup.

The stack trace looks like this and it appears to occur randomly:

0 0xb7629f9e in g_hash_table_iter_next () from /usr/lib/libglib-2.0.so.0

Does anyone know if there has been any bug fixed with a similar coredump? Or maybe someone has an ideea of the root cause?

Thank you!

Any idea about this?

This has been address and we are going to release a new version. You can pull down the latest in the github master to verify that fix it. I will provide more details later today.

rsbells commented 9 years ago

This a duplicate of Ensure that g_context.watchers has a valid value #150 this was causing crashes in renderer. You could make the changes as mentioned in pull request or you could do a clone of all the latest software in dleyne-core, dleyna-renderer, and dleyna-server. We are looking to release version 0.6 in next couple weeks.

Hi Rick,

Thank you very much!

Indeed, to stop the crash caused by the posted Release dbus call I used both patches for #150 and commit 525e167 from dleyna-connector-dbus.

I will come up with a confirmation after I hear from the tester, if this bug will be still open.

Thanks again!

Got confirmation from the tester that the above two patches fix the crash from above. Thank you Rick!
