Hello ConTeXist

I met with great strangeness. When I was looking for a mistake in my 
source text, so I experimented and at one point I renamed myfile so that 
there are "+" in its name. At that moment compilation ran flawlessly. I 
know that the use of + in the filename is relatively non-standard, but 
even so I was surprised
Now everything works fine, but I decided to send it as a curiosity 
rather than to be annoyed by someone.
It's really strange and it took me a long time before I discovered the 
cause of the collapse of the compilation.

Unfortunately I am unable to put together a minimal example, which 
worked, but it is interesting, that compilation will be OK in two cases:

1. when I rename the file to name without "+"

or

2. when images are not to be found (for example when I comment the line 
which contain \setupexternalfigures[directory={flags/}])

Conversely, if "+" is part of the filename, while images are found, the 
compilation will collapse and prints a message that I mention below.

I present here an minimal example (with message list), BUT THAT WILL NOT 
WORK because they do not have my library, but
although the problem probably caused by my library, so it probably is 
not very important at this point because the problem is maybe a bit wider.

Best regards
Jaroslav Hajtmar

Here is my minimal example. When the file called "list-aaa.tex" so 
everything is OK. When the file named "list+aaa.tex" and pictures are 
found, the compilation fails:

\usemodule[../../t-scancsv.mkiv/t-scancsv]

\setupexternalfigures[directory={flags/}]

\def\flagpicture{\externalfigure[\Flag.png]} %\Flag macro is defined by 
my library
\unexpanded\def\tableaction{\expanded{\bTR\bTD\ \flagpicture\eTD\eTR}}

\starttext
\setheader
\setsep{,}
\setfiletoscan{lide.csv}

\bTABLE
\doloopif{\Flag}{~=}{en}{\tableaction}
\eTABLE
\stoptext

And here is message of compilation list:
