"Details" take too long to unfold in crash reporter popup

[Teo]

When some program crashes in Ubuntu and a popup shows up informing you of that and asking whether to send a bug report about the crash, there is a "Details" button (or link).
If you click it, it can take several minutes for the details to show, even when they turn out to be just a dozen of lines of text or so.

There's no way such a long time can be necessary. There is certainly something wrong about it.
