Error accessing user page

Annoying bug in memcached throws errors to users. We are looking for a fix, but haven't solved it yet.
When accessing User:Homo logos page, I always get an error:
MediaWiki internal error. Original exception: exception 'MWException' with message 'Wrong sidebar here!<br /> /wiki/User:Homo_logos' in /var/www/w/includes/Skin.php:2052 Stack trace: #0 /var/www/w/includes/SkinTemplate.php(483): Skin->buildSidebar() #1 /var/www/w/includes/OutputPage.php(1268): SkinTemplate->outputPage(Object(OutputPage)) #2 /var/www/w/includes/Wiki.php(382): OutputPage->output() #3 /var/www/w/index.php(123): MediaWiki->finalCleanup(Array, Object(OutputPage)) #4 {main} Exception caught inside exception handler: exception 'MWException' with message 'Wrong sidebar here!<br /> /wiki/User:Homo_logos' in /var/www/w/includes/Skin.php:2052 Stack trace: #0 /var/www/w/includes/SkinTemplate.php(483): Skin->buildSidebar() #1 /var/www/w/includes/OutputPage.php(1268): SkinTemplate->outputPage(Object(OutputPage)) #2 /var/www/w/includes/Exception.php(167): OutputPage->output() #3 /var/www/w/includes/Exception.php(194): MWException->reportHTML() #4 /var/www/w/includes/Exception.php(292): MWException->report() #5 /var/www/w/includes/Exception.php(351): wfReportException(Object(MWException)) #6 [internal function]: wfExceptionHandler(Object(MWException)) #7 {main}
Purged the page cache directly by editing the URL (?action=purge). It's working now. Thanks.
This is an issue that we have been investigating for the past few weeks with our caching server. Normally you do not get this exception, but you would get an incomplete sidebar. While we are investigating this, we know that about 50 page views will get this error every day; without it, we would not be able to solve it.
