[BUG] Expected Behaviour:
If a pointer is NULL, it should not be passed as a parameter or used

[BUG] Actual Behaviour:
In parser.c, starting at line 711, the variable part is allocated. The return is checked for NULL, but only logged. part is then provided as an argument to strlen, which would result in undefined behaviour. But probably a segfault in most cases.

I'd consider it very unlikely to be run into/fail, but since the check for NULL is already there, might as well not use the NULL? Perhaps the call to logg will halt or set an error, but I didn't notice anything

[BUG] Steps to reproduce:

Device specifics

Hardware Type: rPi, VPS, etc
OS: N/A

Thanks for reporting this glitch! See 69bbbf5 for a proposed fix.

That would fix both of the potential issues in parser.c I noticed. Quick work!
