Re: Crash in rygel-media-export-dvd-container

I noticed there were some asserts before

(rygel:9517): RygelServer-CRITICAL **: rygel_media_object_add_uri: assertion 'self != NULL' failed

Detaching after fork from child process 9539.

** (rygel:9517): CRITICAL **: gupnp_xml_doc_new: assertion 'xml_doc != NULL' failed

Then I wiped cache and rescan once more but it consistently crashes here.

Hi,

that's odd. To get there, it has to properly save the XML file in ~/.cache/rygel/dvd-content which it now can't read?

Hi,

I'm trying out version 0.29.3
