FW: [silva-dev] Upgrade (to 0.9.2) fails with _p_jar

[Benno Luthiger]

Dear JW

I've tried your code completion. However, the upgrade fails on the next line
:-( with:
   print '_p_jar is None for', obj
UnicodeError: ASCII encoding error: ordinal not in range(128)

I'll try a workaround for this error and try the upgrade again.

Regards,
Benno
