maybe the ExtensionManager has some problems modifying localconf.php?
as installing means modifying the line 
$TYPO3_CONF_VARS['EXT']['extList'] = '....'
the EM has to read this line, modify and rewrite it.
sometimes a line has to be copied from static area (before "## INSTALL 
SCRIPT EDIT POINT TOKEN - all lines after this points may be changed by 
the install script!") and the line shows twice with differnt values.
and sometimes a line is more than twice in localconf.php.

changes like this get a comment or the existing comment is modified. 
therefore the EM searches for the string '//'.
But there may be some lines with http://www.... and the commenting is 
modified in a wrong way.

maybe there are some sideeffects on modifying the list of installed 
extensions?
maybe the writes get scrambeled?
