I'm having a problem that I think has something to do with recent version because I don't remember having this problem before. Basically, when I have an error in a Visualforce page, I don't see the error in the Debug Log. I get an email with the error description, but it sometimes takes a long time to send it, so it's not very useful for debugging.

Any clues why an error in a Visualforce page is not showing in the debug log?

Error message example:

I added a System.debug('>>> fails here'); to understand the log better. This is the log from that point on:

```

13:50:50.275|LIMIT_USAGE_FOR_NS|(default)|

```

I can't understand why it doesn't show the null pointer exception or why the log is marked as "success". I used to get a stack at the point of the error inside the log.
