Just updated to 2.5.2, still can reproduce this.

Found out this is only reproducible if you've disabled the recycle bin in your database.

Good to know!!

I've tried capturing a trace with gdb. Hope it's helpful:

gdb.txt

[droidmonkey]

Yes it is helpful and points to exactly what I suspected the problem was. It is directly related to the bug I reported yesterday: #4093

This has been fixed in 2.6
