Steps to reproduce:
1. Open Banshee.
2. Choose "Music" -> "Import Music...".
3. In the dialog, choose "Local Folder" as an import source, then choose "Import Music Source".
4. Select the "Music" directory in my home directory and then choose "Open".
5. Banshee will then crash.

Other information:
I produced the stack trace I just provided in conformity with the information provided on the Banshee website - http://banshee-project.org/Debugging - and I am using development version 8.04 of Ubuntu.

First I tried to follow Ubuntu's guide on providing a backtrace, I executed these - https://wiki.ubuntu.com/DebuggingProgramCrash and https://wiki.ubuntu.com/Backtrace - instructions to provide a backtrace with GDB. However, GDB caused Banshee to crash before I could reproduce the crash which occurs during importing. I have attached the logs of GDB to this bug report as well, I'd like to know why debugging with GDB exactly went wrong.

The backtrace which I provided complains about the absence of taglib-sharp. I searched in Synaptic for "taglib", some results showed, one of them being the package "libtaglib2.0-cil" which was not installed. After installing it Banshee did not crash on importing my "Music" directory anymore.

It seems to me that this bug hasn't got anything to do with Banshee, but that it is Ubuntu's problem that Banshee was incorrectly packaged with a missing dependency for "libtaglib2.0-cil"?
