Hi John,
Just to be sure, you reinstalled TRK after the firmware upgrade, right?
To produce a test case, try to reproduce the problem with a small code and describe the steps you do until the debugger error happens. Oh, yeah, if gdb says any error message, it can be useful. Providing a sis package of this small test case is a good idea too.
If you have any doubt about your testcase, post it here. When we identify if it is a bug and which part is causing it, you'll be able to write a better bug report :-)
