Exporting page to PNG doesn't work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Choose File > Export Page as PNG...
2. Type a file name
3. Save

Expected: The PNG file on the chosen directory.

Actual result: No further dialog.  No PNG file found.

I've tested with Debian Wheezy 64-bit and Ubuntu 12.04 LTS 64-bit, with both 
the extension and Deb version.  Pencil 2.0.3.

( same problem in issue #526 )

Hello , It seems that i have solved this problem.
the reason why can't save the png because the nsIWebBrowserPersist require 7 
parameters on some xulrunner. 

so,correct it is easy :
find 264 line in svgRasterizer.js , change the following line
persist.saveURI(uri, null, null, null, null, localFile); 
to 
persist.saveURI(uri, null, null, null, null, localFile , null );

restart pencil , it works!

Hello, I edited the file 
/usr/share/pencil/content/pencil/common/svgRasterizer.js with this path but it 
don't work :(

[root@ecudesp ~]# cat /usr/share/pencil/content/pencil/common/svgRasterizer.js 
| grep "persist.saveURI"
    persist.saveURI(uri, null, null, null, null, localFile, null);

have you try to clear up cache like this:
 /usr/lib/xulrunner/xulrunner --app /usr/share/pencil/application.ini -purgecaches

Post #4 works for me.

I am still on Ubuntu 10.04 LTS (Pencil 2.0.3)

About the purging of cache, running this:
xulrunner --app /usr/share/pencil/application.ini -purgecachesError: Platform 
version 

gives me:
'1.9.2.28' is not compatible with
minVersion >= 1.9.8
maxVersion <= *

I can get it to start by modifying it to:
firefox --app /usr/share/pencil/application.ini -purgecaches

I have Mozilla Firefox 20.0 installed.

Post #4 works for me too on gentoo. Gentoo use firefox to launch the app (and 
not xul-runner) but you really need to purge the cache.

On gentoo is:
firefox --app /usr/share/evoluspencil/application.ini -purgecaches

The Mozilla docs give this warning about using null[1]:

Important: If you think that you should be passing null here, you are almost 
certainly wrong. null should be passed only when no plausible privacy context 
exists for the URI to be saved, which is an exceedingly rare corner case.

Further to my previous comment, I received confirmation that the suggested 
solution is safe.[1]

I also located an upstream bug about it.[2]
