Hi,

  Try:

M-x semantic-debug-idle-function

  to get a stacktrace.

Thanks!

Aha, an excellent stack trace.  Thanks!  This will take a while for me
to work out through the ctags interface.

Hi Alex,

  Could you try this patch.  I think it will disable TRAMP in order to
check if the file is on the local system before calling external tag
table create functions.  I don't use tramp though, so I can't really
check.

Thanks.
Eric

Hello Eric

No, this patch doesn't helps to fix this error.  But i found, that
following code will fix this error (at least for ctags)

Hi,

Does file-remote-p also work in semanticdb.el as in the below patch?

I mostly didn't know how to check for remote files, but you had the
right function.  In theory, the below will prevent any external parser
from going.  If I push the logic into the ctags parser, then new
external parsers will have the same problem, and no tags will be
found.

Thoughts?
Eric

No - it doesn't work in semanticdb - this was first thing, that i tried. It
seems, that ctags is called from another place. I'll continue
investigations

I got another trace, from which i see, that error occurs in
semantic-parse-region (actually the semantic-ectag-parse-region is called )
called from semantic-fetch-tags.

I'm not sure, that we should disable handling of remote files in
semantic-fetch-tags.  I'm currently thinking how we can run ctags on
temporary file, created by tramp, may be we need to look to remote files
handling in ECB
