The crash is caused by the plugin, directly. See this trace:

BTW: plugins are disabled on the dialog box (no little check box is selected!). Still the plugin gets loaded. NICE.

[kazehiri]

Mmmm...is a plugin's problem no?You know if you can report bugs to
Adobe? The fault is yours, if they did open source ...I will try to
report it.Thanks again.

One problem I do see is that I disabled the plugins usage in Arora, and still it's getting loaded.

Does anyone have a clue?

[Benjamin Meyer]

Yes, in older versions of qtwebkit the plugin was always loaded even when it was not used.

If you use a newer version of qt or qtwebkit this problem goes away.

[kazehiri]

So if you compile Arora with the latest version of QtWebkit will solve
the problem. Can anyone do that?. I am somewhat confused, if that
solves the latest versions of QtWebkit, whose is the problem?, Flash
or QtWebkit..?

There are two bugs

1- flash crashes, flash is now expecting qtwebkit to do something it doesnt
2- qtwebkit loaded flash into memory no matter what

I am using Qt 4.6.3, I can assume this is fixed only in Qt 4.7...?

[kazehiri]

So one solution would be to compile Arora QtWebkit 4.7, right?. A
separate question, can you make plugins Arora insulate?. While it may
make a return less light ...
