unrecoverable error when running update.php

Hi,

when running update.php after upgrading to 5.x-1.3, I'm getting:

An unrecoverable error has occured. You can find the error message below. It is advised to copy it to the clipboard for reference. Please continue to the update summary

Fatal error: Allowed memory size of 83886080 bytes exhausted (tried to allocate 1048576 bytes) in /var/www/drupal/sites/all/modules/quotes/quotes.install on line 404
...
The update process was aborted prematurely while running update #9 in quotes.module. All other errors have been logged. You may need to check the watchdog database table manually.

The following queries were executed
