Warnings during compile; MSN Errors when loaded

[anlag]

Had some initial problems compiling, but after installing the following two libs it finally compiled:

libglib2.0-dev
libpurple-dev

However, there were some warnings; compilation output is appended. I'm able to load the plugin, but a short while after turning it on in Pidgin, I start getting the following error in repeated pop-up windows:

"MSN Error: Friendly name changes too rapidly"

These keep appearing, and it does not appear like my currently playing song is being shown on either protocol out of ICQ, MSN and Gtalk. When turning off the plugin, the errors cease.

Using Ubuntu 8.10 64-bit version.
