NullPointerException after creating a KPI

Description of problem:
NPE just after dropping a new KPI in a page.

The data source returns 44 records. After dragging, when just dropping the KPI, it takes some time (seems to load all records, as the time taken depends on the size of the table).

Version-Release number of selected component (if applicable):
Compilation against 23th October commit (commit SHA Id a6ad297262034c976f2c3618bed3300358984021, corresponding to "BZ-1021830 - Unexpected Error (CSRF token missing) when clicking go back in Import Dashboards panel".

How reproducible:
Don't be able to reproduce it, but each time we open this page, a red cross image associated with an exception panel is showed.

If we try to delete the page, seems to do it (closing the page and navigating to the main one), but on the combo box still appears and, if selected again, is showed again (so it has not been properly deleted).

Steps to Reproduce:
Not easy to reproduce
