Package: linux-image-2.6.30-2-686
Version: 2.6.30-8
Severity: important

Hi

When I try to build eclipse 3.5 from source the compile is usually interrupted by the kernel deferencing
a NULL pointer in (as far as I can tell) my file system driver. I do not see this during "normal" usage[1].
The attached log contains two separate deferences from two separate build attempts.

This may not be of relevance, however:
 * The base system is testing while I build in cowbuilder against sid.
   - I have not tried to run the build directly in my base system (outside cowbuilder).

Thank you in advance,
~Niels

[1] I do not really use it for anything besides building packages.
