Profiler error when increasing PROFILER_MAX_DEPTH

[miki725]

With default profiler max depth of 10, everything works as expected. However when increasing that number to higher threshold starting to get these:

ValueError: need more than 1 value to unpack

I assume since it works with lower depth, configuration is good. Is this a known bug or might be something off in my config?

[miki725]

adding a breakpoint here is the content of self.func right before the exception:

(Pdb++) self.func
('<string>', 1, '<lambda>')
