#422 Could not resolve variable in debuuger

[Jie Yang]

When I debug a big project using PyDev and stop at any break point, no variables can be displayed. It shows:

-Globals Global variables
.Error Could not resolve variable
.Error Could not resolve variable

However, when I debug a simple project (a script with few lines), it works fine.

More info:

- System: windows XP SP2
- Eclipse version: 3.2.1
- PyDev version: 1.2.6
- PyDev error log:

When I use Python2.3 as the interpreter, the debugger works fine.
However, when I use Python2.4, the problem always happens.
I also tried Eclipse3.1.1 with PyDev 1.2.6 and Python2.4, but found the same problem.

Do you have some sample code where this could happen? Which libraries do you use (may be related to somethings specific -- e.g.: if you use psyco you may have this kind of trouble because psyco will replace frames, so, you cannot use a debugger with it).
