Segmentation fault on every checkout

Hi,

I cannot use the svn client on one of my computers any more. Every time
I try to check out something svn segfaults. I've tried different svn
repositories, all of them via https and several places to check the code
out. Everything results in a segfault.

For example the backtrace for the call:
root_at_little-tux:/usr/local/src# svn co
https://svn.osl.iu.edu/svn/pbgl/trunk pbgl-trunk

is:
#0 0xb7be34b4 in svn_io_get_dir_filenames () from
/usr/lib/libsvn_subr-1.so.1
#1 0xb7e640af in ?? () from /usr/lib/libsvn_wc-1.so.1
#2 0xb7e64c9c in svn_wc_crawl_revisions3 () from /usr/lib/libsvn_wc-1.so.1
#3 0xb7ecdf0a in svn_client__update_internal () from
/usr/lib/libsvn_client-1.so.1
#4 0xb7ea50c9 in svn_client__checkout_internal () from
/usr/lib/libsvn_client-1.so.1
#5 0xb7ea5404 in svn_client_checkout3 () from /usr/lib/libsvn_client-1.so.1
#6 0x0804d307 in ?? ()
#7 0x080549b5 in ?? ()
#8 0xb76a8685 in __libc_start_main () from /lib/tls/i686/cmov/libc.so.6
#9 0x0804c2c1 in ?? ()

After the segfault the working copy is locked. Trying to clean it up
results in this output:
root_at_little-tux:/usr/local/src/pbgl-trunk# LANG="" svn cleanup
svn: Can't convert string from native encoding to 'UTF-8':
svn: ?\248

I'm using the Ubuntu Intrepid Ibex packages. On my other machine they
work, so I suspect it must be some special configuration on this
computer that is causing this segfault.

root_at_little-tux:/usr/local/src/pbgl-trunk# LANG="" svn --version

Is this a know bug or should I report it?

Thanks for the help!
