An error occurred during the processing of . The resource object with key 'ResolveBugPageTitle' was not found.

This error is caused by missing resource files starting with the filename "tsa.*" which for some reason i noticed were absent from the web directory "C:\Inetpub\wwwroot\wss\VirtualDirectories\{your website port number}\App_GlobalResources" on the web server. Here are the steps to fix this issue:
1) Browse the directory in 12 hive - C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\CONFIG\Resources
2) Copy all the files whose names starts with "tsa.*" and paste these resx files into your website directory "C:\Inetpub\wwwroot\wss\VirtualDirectories\{your website port number}\App_GlobalResources"
3) Browse to the instance of your Bug Tracking site's "bugdefault.aspx" page
4) Click on the small yellow, green buttons and EUREKA! - the Bug resolution page appears and everything functions as expected...
