in Config.class.php checkPmaAbsoluteUri() can detect the PmaAbsoluteUri, but it dependence on PMA_IS_WINDOWS, but PMA_IS_WINDOWS didn't initialized before loading config, since it can't convert backslash to slash, pma got a wrong PmaAbsoluteUri such as http://example.org\/ causes many action goes wrong.
to resolve this bug need use checkWebServerOs() initialize PMA_IS_WINDOWS before load config, or redetect the PmaAbsoluteUri again after using checkWebServerOs()
You report this for "latest subversion", could you specify which exact SVN revision and are you talking about trunk?
yes, the trunk, i found https://phpmyadmin.svn.sourceforge.net/svnroot/phpmyadmin/trunk/phpMyAdmin in http://www.phpmyadmin.net/home_page/improve.php isn't it?
i'm in vacation now, so i can't check the exactly revision, but it should be the latest revision before i submit this report
Fixed in subversion, thanks for reporting.
