What happens is this:

+ mv -f 28668 /var/lib/texmf/language.dat
+ db_get tetex-bin/hyphen
+ echo 'GET tetex-bin/hyphen'
+ local 'IFS=
'
+ local _LINE
+ read -r _LINE
+ RET=french[=patois], ngerman[=naustrian-neue_Rechtschreibung]
+ return 0
+ IFS= ,
+ lang=french[=patois], ngerman[=naustrian-neue_Rechtschreibung]
+ sed -e 's/%! french/french/' /var/lib/texmf/language.dat
+ sed -e 's/%! =patois/=patois/'
+ mv -f 28668 /var/lib/texmf/language.dat
+ sed -e 's/%! ngerman/ngerman/' /var/lib/texmf/language.dat
+ sed -e 's/%! =naustrian/=naustrian/'
+ mv 28668 /var/lib/texmf/language.dat

I think the problem is with the expression "$LDAT_$$".  I think what you
wanted was to concatenate $LDAT, "_" and $$, but this expression is expanded
as "$LDAT_" (which is empty) concatenated with "$$" (expanded to the PID).
This would create a file in the cwd, which is probably what caused te
problem.

I suggest using tempfile or mktemp from debianutils (which is essential).
