libglib2 error with aRts

[David Jarvie <lists@astrojar.org.uk>]

I run a self-compiled KDE (using the latest vanilla KDE sources) on etch. 
Recently, aRts sound has not worked since an upgrade to libglib2.0-0. The 
console error message when I try to open a sound file is:

***MEMORY-ERROR***: [13057]: GSlice: failed to allocate 248 bytes (alignment: 
256): Invalid argument

When I tried downgrading to libglib2.0-0_2.8.6, aRts worked again, but because 
that breaks other packages, I have reinstalled the current 
libglib2.0-02.10.2-1, even though aRts fails.

How can I make aRts work with the new libglib2.0-0? I have tried recompiling 
aRts more than once, but it doesn't help. Presumably the official Debian arts 
package works, so it must be possible to fix this.

If there is a better list to post this question on, please let me know.
