#3373: TracLink 'query:' leads to a Trac IndexError
---------------------------------+------------------------------------------
Reporter: [EMAIL PROTECTED] | Owner: jonas
Type: defect | Status: new
Priority: normal | Milestone: 0.10
Component: wiki | Version: devel
Severity: normal | Keywords:
---------------------------------+------------------------------------------
If the following TracLink is inserted in a page :
{{{
[query: Query]
}}}
this leads to the Python error below. A workaround is :
{{{
[query:? Query]
}}}
IMO, Trac should take care of adding the `?` in case the query string is
empty.
