Description

When switching interfaces, if the new interface fails to start, Audacious crashes with a null dereference.

Presumably it should attempt to recover by switching back to the old interface. An example for reproducing this issue would be to try to switch to the new skins-qt plugin without having any skins installed.

History

#1 Updated by John Lindgren almost 9 years ago

I can't reproduce this on latest Git master. What is the backtrace?

I see:

WARNING skin.cc:276 [skin_load]: Unable to load skin (/usr/share/audacious/Skins/Refugee).
WARNING skin.cc:276 [skin_load]: Unable to load skin (/usr/share/audacious/Skins/Default).
ERROR plugin.cc:101 [load_initial_skin]: Unable to load any skin; giving up!
ERROR plugin-init.cc:251 [enable_single]: Winamp Classic Interface failed to start; falling back to Qt Interface.

And then the Qt UI comes back as it should.

#2 Updated by Ariadne Conill almost 9 years ago

#3 Updated by Ariadne Conill almost 9 years ago

If you were wondering, `%rax` is a nullptr.

#4 Updated by John Lindgren almost 9 years ago

Does this commit help?
https://github.com/audacious-media-player/audacious/commit/ff06739ec7f0886e823ed356b998a587ce10d8c8

#5 Updated by Ariadne Conill almost 9 years ago

No, I am still seeing the same backtrace on a clean build.

#6 Updated by John Lindgren almost 9 years ago

That's unfortunate. My guess is, it's a bug in Qt.

#7 Updated by John Lindgren almost 9 years ago

Subject changed from Audacious 3.7-devel crashes when a new interface fails to start to Audacious 3.7-devel crashes when a new interface fails to start (OS X only)

#8 Updated by John Lindgren over 8 years ago

Subject changed from Audacious 3.7-devel crashes when a new interface fails to start (OS X only) to Crash in QCocoaMenuBar when switching UI (OS X)

#9 Updated by John Lindgren about 7 years ago

Status changed from New to Rejected

Closing OS X-specific bugs since development on that OS seems to have stalled.
