I recently upgraded to 2.8.4 from 2.7 and a plug-in that I deactivated and whose directory I deleted is triggering an error message:
"The plugin wordpress-single-file-php-gallery/ has been deactivated due to an error: Plugin file does not exist."
In this case, I WANT the plug-in to be deactivated, but I do not want the message to continue to pester me. It's a minor bug, but it is slightly irritating.
Thanks for the suggestions.

Five months later and the error message is still there.
Now up to WordPress 2.8.6.
Re-upload the plugin, activate it, deactivate it, then delete it again.
It sounds like it didn't uninstall cleanly.
Also you should try WP 2.9.1 eventually ;)

Okay, I seem to have fixed this, but the repair is not for the faint of heart.
Somehow the WordPress Single File PHP Gallery plugin registered itself as active, but did not UNregister itself when it was removed from my system. So, it was stuck in the wp_options MySQL table. To get it out, I used phpMyAdmin and manually edited the entry.
Here is the process I followed:
1. Backed up my database!
2. Searched the table, wp_options, for the option_name "active_plugins".
3. The option_value for this option_name was an array of all the active plugins:
a:16:{i:0;s:19:"akismet/akismet.php";i:1;s:43:"broken-link-checker/broken-link-checker.php";i:2;s:33:"category-magic/category_magic.php";i:3;s:36:"contact-form-7/wp-contact-form-7.php";i:4;s:26:"dm-albums/wp-dm-albums.php";i:5;s:21:"exec-php/exec-php.php";i:6;s:43:"flexible-navigation/flexible-navigation.php";i:7;s:41:"gd-pages-navigator/gd-pages-navigator.php";i:8;s:29:"nextgen-gallery/nggallery.php";i:9;s:36:"random-image-widget/random_image.php";i:10;s:47:"really-simple-captcha/really-simple-captcha.php";i:11;s:39:"simple-ldap-login/Simple-LDAP-Login.php";i:12;s:49:"vipers-video-quicktags/vipers-video-quicktags.php";i:13;s:43:"wordpress-link-directory/link-directory.php";i:14;s:34:"wordpress-single-file-php-gallery/";i:15;s:29:"wp-recaptcha/wp-recaptcha.php";}
4. I guess that the first number (a:16) indicated the number of plugins in this array and noticed that the plugins counted from 0 to 15. That is, i:0 to i:15, for a total of 16 plugins. So, I changed a:16 to a:15.
5. Then I deleted:
i:14;s:34:"wordpress-single-file-php-gallery/";
6. Then I altered the plugin that was after it in the array to a new number -- changing
i:15;s:29:"wp-recaptcha/wp-recaptcha.php";
to
i:14;s:29:"wp-recaptcha/wp-recaptcha.php";
7. Then I saved my changes, fearing that I'd borked the MySQL database, but so far it seems to have merely removed the Single File plugin.
I can't guarantee this technique will work for others, but I post it here for anyone else like me who is annoyed with the WordPress Single File PHP Gallery plugin (or some other misbehaving plugin) not properly UNregistering itself.
That's weird. Normally that shouldn't be possible -- one of the checks for active plugins is, I THOUGHT, seeing if the folder exists and if not, deleting from that entry.
