Bug#1002459: lp: Unsupported document-format "application/x-idx-doc" when printing txt files

[Thomas Arendsen Hein]

Package: printer-driver-indexbraille
Version: 1.2.3-2
Severity: normal
X-Debbugs-Cc: tho...@intevation.de

Dear Maintainer,

during "apt-get dist-upgrade" from Debian buster to bullseye, the package
printer-driver-indexbraille 1.2.3-2 has been installed.

Due to this, the following problem started when trying to print simple text
files named *.txt. To reproduce:

$ echo > foo.txt
$ lp foo.txt
lp: Unsupported document-format "application/x-idx-doc".

Workaround:
$ cat foo.txt | lp

Context in /var/log/cups/error_log (after "cupsctl --debug-logging"):

The detection happened due to an entry for "txt" in
/usr/share/cups/mime/indexbraille.types

Removing the package solved the problem for me, but for people who need this
package installed or who don't know that this causes the problem, this should
be solved. My suggestion would be to remove the entry for "txt" from the file.

Best Regards,
Thomas Arendsen Hein
