Steps to reproduce:
1) Install CRM and Marketing Campaigns
2) Create at least one company & contact in CRM
3) Create a search that returns at least one contact in CRM
4) Create a marketing campaign that operates on Partner Addresses
5) Create an activity within this campaign that is the start activity, set its condition to False, don't check "Don't delete workitems"
6) Create a segment for the campaign based on the search from step 4
7) Start the campaign and the segment
8) Synchronize segment manually
9) Click on the green arrow for the workitem
10) The workitem is deleted since its run condition wasn't met, but the screen is not updated. So it remains on the screen and the green arrow can be clicked again.
11) Clicking the green arrow again will attempt to run a workitem that no longer exists and result in the following stacktrace:

This is indeed not very user-friendly, but it is also to be expected, given the non-standard implementation of the "Process" button.
Buttons do not usually cause the deletion of the underlying record, this is normally accomplished via the Delete button of the UI.
I suspect this issue is web-only. It's not an addons issue in any case, because calling a function on deleted records is not supported.
Now, as clicking on a button should cause a refresh of the record afterwards, it might be feasible in the web client to detect the fact that the record has gone missing (upon refresh), and update the UI accordingly. To be confirmed by the web team.
