IndexError: list index out of range

[dneise]

SH was calling me every hour or two during the last night since we use sfc 0.4.1 for the first time.

I was able to reproduce the problem first time this way:

while True:
    print(time.asctime(), sfc.main_page())

Got this:

Tue Jan 23 08:03:01 2018 single-pe(179) [104/02:09]
Tue Jan 23 08:03:02 2018 single-pe(179) [104/02:09]

IndexError: list index out of range

So it happened just after the single-pe run in the end of the night ... maybe this is the reason why it called me only sometimes ...

If we set fallback=True ... then we do not get an exception.

So this is is not an fsc issue.
