Package: python-rdflib
Version: 2.4.2-1+b1
Severity: serious
Justification: Breaks build of another package

Building enigmail 1.0.1-2 on mipsel fails with "Bus error":

https://buildd.debian.org/fetch.cgi?pkg=enigmail&arch=mipsel&ver=2%3A1.0.1-2&stamp=1275423629&file=log&as=raw

I've reproduced this on a qemu-emulated mipsel machine. The problem 
is the script /usr/bin/install-xpi that uses rdflib to parse the file
install.rdf.

I've reduced install-xpi to the method that shows the problem, and added 
printf debugging to find the failing method. 

The output of this script on mipsel is

$ ./install-xpi 
gei 1 install.rdf
gei 2
gei 3
gei 4
gei 5
Bus error

So the problem occurs when calling rdf_graph.query().

I have no experience at debugging python applications, especially not when
system level bugs are involved, so I can't debug this issue further.

I can make the qemu image I used available. It is based on the lenny image by 
Aurélien Jarno.
