GnuCash crashes when importing QIF file

[Arkadi Gelfond]

I'm using GnuCash ver.  2.0.1-3   built from r14585 on 2006-09-13,
running on Debian Etch(testing)

GnuCash crashes now on the last step after 'Enter the currency used
for new accounts'. It did not happen before, in fact I was able to
import most of my data using numerous QIF files, but now it crashes
even if I try to import the same QIF files into empty file.

here is the trace I found in the /tmp:


gnucash: /usr/lib/gnucash/libgnc-backend-postgres.so: cannot open
shared object file: No such file or directory
