Maintengine TypeError crash

[Morten Brekkevold]

On NAV 3.13.0, the maintengine cron job has been observed to crash. Apparently it may happen if a device is assoicated with several simultaneous maintenance tasks.

Traceback looks like this:

> Traceback (most recent call last):
> File "/usr/local/nav/bin/maintengine.py", line 45, in <module>
> main()
> File "/usr/local/nav/bin/maintengine.py", line 39, in main

> str(curr_event['maint_end'])))
> TypeError: not all arguments converted during string formatting
