Similar, but not identical problem here. It seems to happen mainly when
Skype has been idle for some time, when someone sends me a chat message
everything hangs for up to five minutes.
Software:
Ubuntu Dapper running:
Kernel 2.6.15-27-amd64-k8
Skype 1.3.0.53_API installed in a 32-bit chroot from .deb package on
skype.com
Proprietory ATI (fglrx) modules
Hardware:
Acer Ferrari 4005WLMi with:
AMD Turion 64 CPU
1GB RAM
