Thanks jurij for your help.

Some further notes on the dissasemble command I ran into while trying to
1: it seems you have to explicitly select a range unless you want a
2: if you have debug symbols installed you have to use "info frame" to
get the address of the program counter
3: the addresses were different on my system, i'm not sure whether this
was because my system was slightly out of date at the time or because of

build log has a huge number of cast alignment warnings :( worse the file
in which the error occoured is generated at webkit build time and is
therefore not available in the webkit source package. I don't have the
resources to build webkit on sparc in a reasonable time.
Since testing an unstable have different versions of both seed and
webkit. I decided the next thing to try was to build both testing's
version of seed and unstable's versions of seed in both testing and
unstable to try and narrow down which package caused the regression.
However all four combinations failed with a bus error so it seems this
regression happened before the version of webkit that is now in testing.
I'm now marking this bug as affecting the version in testing as well.
at webkit build time? I didn't spot anything on a quick look at the log
but the log is massive so it's possible I missed it.
