[Bug 376121] [NEW] audacious hangs when tries to add rar-archive to playlist

[Dmitry Grebeniuk]

Public bug reported:

Binary package hint: audacious

1.
$ lsb_release -rd
Description:	Ubuntu 9.04
Release:	9.04

2.
$ LC_ALL=C apt-cache policy audacious
audacious:
  Installed: 1.5.1-4ubuntu3
  Candidate: 1.5.1-4ubuntu3
  Version table:
 *** 1.5.1-4ubuntu3 0
        500 http://md.archive.ubuntu.com jaunty/universe Packages
        100 /var/lib/dpkg/status

3.
I'm creating file /tmp/somearchive.rar with these commands:
$ sudo apt-get install rar
$ cd /tmp
$ touch somefile
$ rar a somearchive.rar somefile
I'm trying to add /tmp/somearchive.rar by pressing Ctrl-Ins, then selecting file in dialog (or selecting any directory that contains any rar-archive), then clicking "Add" button.
I expect that audacious will skip this/any rar-archive or, less likely, will add the contents of archive to playlist (however, I don't need such functionality, so skipping the archive would be enough for me).

4.
After clicking "Add", audacious begins to use cpu (60%user, 40%system approx, on my system) until interrupted (I've tried to wait about 20 minutes), without any other effects, and it stops redrawing GUI.
I ran it (either from audacious-dbg package or from audacious; the picture is the same, except symbols) under gdb and hit Ctrl-C when audacious was eating cpu:

^CAudacious has received SIGINT and is shutting down.

Maybe it will be interesting for you: ip's from first three lines
doesn't match any shared library's range that gdb show with "info
sharedlibrary".
