[Rt-devel] Wide character in subroutine entry at (RT2toRT3 error)

[bartosz.cieplik at comarch.pl]

Hello, i have some problems with re-importing data to RT3, data which has
been dumped from RT2.
At first time dump from RT2 and import to RT3 end with success, however
during second dump-import(the same environment, OS etc.) i encountered this
problem: 

[Sat Mar 12 16:25:32 2011] [crit]: Wide character in subroutine entry at
/usr/lib/perl/5.10/Encode.pm line 174.
(/usr/share/request-tracker3.8/lib/RT.pm:389)
Wide character in subroutine entry at /usr/lib/perl/5.10/Encode.pm line
174.

To be more specific:
- i was dumping(at the second time of course) from RT2 using 'since'
option.
- attachments and tickets includes polish letters, encoding is iso-8859-2;
- at the first time whole procedure(dumping whole database without 'since'
option, import to RT3) end with success, even polish signs was dumped and
exported properly.
I've tried use LANG=C option during dump and export, without success.

Please help.
Thanks in advance!
