First off, I depend on the ability to import large numbers of regular 
*.txt files into zim-wiki.  In general there are few if any issues.  I'm 
not aware of any import/conversion process, and simply copy files into a 
subdirectory of ~/Notebooks.

So a key question is what if any guidelines do we have on importing 
general text files to zim.  A distinctive suffix (e.g. .data) might be a 
reasonable approach.  As it is, I think files in the zim notebook 
hierarchy that aren't directories and don't end in .txt are ignored.

The one issue I discovered long ago is that any *.txt file with a first 
line like "abc: def" causes export to crash.  lines like:
	"abc: def hij"
don't seem to cause a crash.  It you just try to open such a file, a stack 
trace and warning appear, but zim does not crash.

Notes I made while tracking down the origin of the crash
In zim/formats/__init__.py parse_header_lines(), line 1769 is where the 
exception occurs.  The two words (abc: def.) seem to be treated 'header' 
and 'value'.  It may be due to uneasy coexistence of files created in the 
notebook and regular files imported into it.

This is the typical stack trace from a crash in export.
