Python keeps crashing while using Tamper #15

Python keeps crashing, see the two malloc breaks:

TBH I don't even know how to start debugging this... I'm not so familiar with Python.

Is this a log file maintained by Python? How long after running tamper did you get this error? (Assume tamper starts running the when Chrome loads up)

Maybe Tamper's Chrome extension's log will tell us more? Could you please do the following:

And copy & paste the console messages here?

seyDoggy commented 10 years ago

How long after? Can't say atm since I can't reproduce right now.

I mainly wanted to see if there are a lot of random disconnects between the Chrome extension and the Python one, but it looks like it's running fine.

saalmaan commented 10 years ago

@dutzi I have got two system crashes today and each time I investigated it was python crashing, I will report back with full system log

dutzi commented 9 years ago

@saalmaan, did you experience any crashing lately? @seyDoggy, where do you see this log file?

seyDoggy commented 9 years ago

I haven't been using it all that much.

I havent see any crashes lately and that is may be due to the fact that I am also not using tampre not that much, I will report back if I see any issue, lets keep this issue open for moment.
