Description

Assume the following scenarios:

Scenario A)
A template has the following line:
#parse("never-found-template.vm")

Scenario B)
A template has the following line:
#parse($nonsense)

Assume further, that neither the "never-found-template.vm" is present nor the variable "$nonsense" is set.

In scenario A) the log reports "#parse(): cannot find template 'never-found-template.vm', called from template ... at (1, 1)"
In scenario B) the log says "#parse() null argument"

Problem:
In scenario B), having multiple nested #parse-Statements, it's hard to find the error finally.

Sugestion / Feature request:
Include source information and line numbers when reporting "#parse() null argument" - analogous to scenario A)

Thanks and kind regards
