Startup Applications not working after upgrade to Karmic

[Colin Law]

Hi

I have upgraded a 9.04 desktop system to 9.10 and now entries I have
added to System, Preferences, Startup Applications no longer start.
These are to thunderbird and gpodder.  They work fine if I manually
start them.
I have looked in various log files for clues but found none.

I have another 9.10 (clean install) where the startup apps work ok.

Any suggestions as to what the problem may be or where to look for
clues gratefully received.

Colin
