It works fine with ext3 :)
That's because ext3 has per-file block preallocation
disabled.
When you truncated your file, the blocks remained preallocated
on behalf of the file, and were hence considered "used". For
some reason, a subsequent attempt to allocate blocks for the
same file failed to use that file's preallocated blocks.
It's an arguable bug in ext2 and, as you've seen, the consequences
are bad. Your applications _are_ a little bit buggy,
because they can't assume that just because they
truncated the file, that space will remain available to
them.
Maybe someone would like to wade through screenfuls of icky
single-char identifiers and fix it?
