- Revision ID: edam@waxworlds.org-20110530192017-5c09k4kgpov02gja
- added checks for Doit.this == null when handling dialog buttons (I managed to abort an import as a duplicate contacts dialog was shown, but can't reproduce it now)
- added line no.s to vcard parsing errors
- update progress bar after a contact is imported, not before
- fixed bug introduced in last commit where a contacts were imported after finaliseVcard()ing failed
- don't show unknown encoding errors for vcard fields that we don't care about (which ignores base64 encoded photos, for example)
- added line no.s to vcard parsing errors
- update progress bar after a contact is imported, not before
