If you install the TWiki:Plugins.TopicTranslationsPlugin you will get this error:
Use of uninitialized value in pattern match (m//) at /var/www/twiki/lib/TWiki/Plugins/TopicTranslationsPlugin.pm line 266.
when run mailnotify or tick_twiki.pl.

This error is on this line:

if (($ENV{SCRIPT_NAME} =~ m#/view(auth)?$#) and (! $ENV{QUERY_STRING})) {

You can simply add this line before the line 266:


Is important not to trow unuseful warnings because this will generate logs to the webmaster. A lot of log will difficult to see really important errors and may be a security problem.

Other plugins may have this same problem...
May be better to add $ENV{SCRIPT_NAME}='' if ! $ENV{SCRIPT_NAME}; inside a base twiki file to clean this problem.

No, it would not. The fact that $ENV{SCRIPT_NAME} is undef is used in some places to detect when the script is being run from the command line.

The plugin should not fail when it is undef.

Reassigned to TopicTranslationsPlugin.
