In the new 3.22 exists another example:

koha-tmpl/intranet-tmpl/prog/en/modules/about.tt

lines 262-264

<td>You are missing the <strong>&lt;upload_path&gt;</strong> entry in your koha-conf.xml file. Please  add it, pointing to the configured file upload directory for your Koha instance. Also note that you need to properly set the <strong>OPACBaseURL</strong> preference for the file upload plugin to work.</td>

The generated PO file

#: intranet-tmpl/prog/en/modules/about.tt:255
#: intranet-tmpl/prog/en/modules/about.tt:262
#, c-format
msgid "You are missing the "
msgstr "Falta la entrada "

msgstr "&lt;upload_path&gt;"

msgid ""

msgstr "OPACBaseURL"

#: intranet-tmpl/prog/en/modules/about.tt:264
#, c-format
msgid "preference for the file upload plugin to work. "
msgstr ""

Finally this end up in a nonsensical translation

IMHO, If developers can really take into consideration not to use this kind of paragraphs and -if possible- modify the coding guidelines in wiki page to reflect this.

Or if there are another option to do life easy for translators?...
