[TYPO3-english] RealURL + sr_language_menu produces wrong path segments

[Victor Livakovsky]

Hi, list.

I have a multilanguage web with RealURL enabled. And here is the situation:
speaking URL path segment of a German page (default) is 'german-page',
Endlish page has 'english-page' in path segment.

When I'm viewing German version of a website, everything is fine. German 
page displayed as www.domain.tld/german-page.html and english page is 
www.domain.tld/en/english-page.html
Once I switch to English version of a page, I get 
www.domain.tld/en/english-page.html as English page and 
www.domain.tld/english-page.html as German page!
When accessing www.domain.tld/english-page.html (switching back to German 
version) I get www.domain.tld/en/english-page.html as English page and 
www.domain.tld/german-page.html as German page in any menu (but url is still 
www.domain.tld/english-page.html).

Same thing, if I access: www.domain.tld/german-page.html?L=1 - German page 
then displayed as www.domain.tld/english-page.html

I've found similar problems in this list, but they were because of different 
domains were used for different language version. My web is multidomain 
also, but same domain is used for both languages.

TYPO3 4.2.11
RealURL 1.7.0

What may be a reason of it? And how can I fix this issue?
