no, it shouldn't: do you base this suggestion on knowledge of Lynx source?

no & yes, respectively.

 lynx.cfg  (tidied a bit) says:

# The MIME_type:viewer:XWINDOWS definitions listed here in  lynx.cfg
# are among those established via  src/HTInit.c .  For the image types,
#  HTInit.c  uses the XLOADIMAGE_COMMAND definition in  userdefs.h  or above.
# You can change any of these defaults via global/personal mailcap files.
# Assignments made here will be overridden by entries in those files.

so an entry in  lynx.cfg  would have an effect
only if i were to drop the line in  .mailcap , which would affect eg Mutt.

to emphasise the basics of the problem again:
(1) it's intermittent between (but not within) Lynx invocations;
(2) it occurs with local, as well as remote, files;
(3) the error blurb refers explicitly to the temporary directory/file,
which it cannot access for some reason: NB the random tmp directory name
was added to Lynx a few years ago to remove a race-condition vulnerability;
(4) whatever the cause of the problem, Lynx should not crash.

i'm now using 2-8-5dev.5 (the problem was with 2-8-4dev.19 ),
so i will report on tonight's newsreading session tomorrow morning.

PS could we please change the solecism `XWINDOWS' to the correct `XWINDOW'?
