Pagination doesn't navigate very well, in search context

[FxNION]

Execute a query that can retrieve a lot of results, more than 10
When clicking either on Next or Previous in pagination element, the url looks curious with some ";" (so converted in %3b) and doesn't work:

​http://xxxxx/elgg/pg/search?q=YYYYY&%3Blimit=10&%3Boffset=0&%3Bsearch_type=tags&offset=10

When clicking on a page number in the pagination element, a page displaying Error "Please enter a query to search". The url shown is just: ​http://xxxxx/elgg/pg/search?offset=ZZZ

In Admin/User administation, all seemms ok concerning the pagination.
