Subject: Issue #1423 - ensure that XMLTV grabber search does not crash.
X-Git-Tag: v3.5~246
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=563b8f8c51a4fa0ee33c0ae8786f3fec84f70b4d;p=thirdparty%2Ftvheadend.git

Issue #1423 - ensure that XMLTV grabber search does not crash.

It appears that if paths are duplicated in the PATH env variable the
internal search algorithm failed to detect this and could crash due to
an assert in the internal modlue registration code.
