audacious crashed with SIGSEGV in mowgli_dictionary_retune()

[hype]

Binary package hint: audacious

Audacious crashed when i dragged a mp3 file on the playbar.

IT seems that audacious has some issues recently: i have issues when launching a file while audacious isnt opened; instead of playing the track i clicked, it plays the latest track played before. (didnt check for bug reports yet)

It appears that the mowgli hashtable lacks a definition for file:// or something. Not sure why mowgli would segfault rather than just return false or something, but the attached patch should prevent mowgli from being accessed for file://'s. Dunno if this is an appropriate fix, probably needs more review by upstream.

[William Pitcock (nenolod)]

umm. no. the only time mowgli_dictionary_retune() will crash is if the dtree memory is corrupted, which means this reporter has bad RAM, or something really bad is going on elsewhere.

this is not happening in Debian, so I blame your extra patches...

Where can 105_custom_uri.patch be found? By reading the short description of it, I have doubts that it is a good fix. The SIGSEGV in mowgli_dictionary_retune() is due to heap corruption, not due to looking up missing keys in a mowgli dictionary.

That's the one from comment 4.
It won't suffice.

If you want to do your users a favour, evaluate Audacious 2.2 (and see how many of the patches in the Fedora packages help you). Meanwhile, 2.3 has been released, but it isn't a bullet-proof upgrade option.
