Recurrent "java.lang.NullPointerException" errors (HTTP Status 500)

Hello all,
We have a recurrent "java.lang.NullPointerException" errors (HTTP Status 500) that happen on random occasions but mostly when we are "picking" to hard on the platform such as : cancelling uploads, quickly closing the browser without waiting for the current action to complete, use cancel or back buttons when response is too slow etc... We where having this issue very often with 5.2 RC1. Since we switched to 5.2 final it has been much more stable but we still have this error from time to time. I have attached a screen capture and the related log. Is the problem with the stability of the platform or is it related to our installation or server hardware (AMD Athlon Dual Core Processor 4850e with 2 GB Memory on Fedora Core 7) ? Thank you for your answers.
