Where the only difference is (note the escaped \; in one of them):

PHOTO;VALUE=URI:data:image/jpeg\;base64\,/9j/4AAQSkZJR...
PHOTO;VALUE=URI:data:image/jpeg;base64\,/9j/4AAQSkZJR...

Import the file into a new address book.

Right after importing, both contacts have a profile picture in the list and within the contact details:

Screencast.from.2024-10-20.02-05-10.webm

Now, after refreshing the view (or, basically, any time you open the contacts app afterwards), the escaped contact is not displayed on the list, nor when clicking the first time to see the contact details:

Screencast.from.2024-10-20.02-06-57.webm

The browser's console shows a 404 error on contact list load:

EDDD3AFC-D6B0-4D59-862E-D91CCA43E090.vcf:1
  GET https://domain.com/remote.php/dav/addressbooks/users/User/asdf/EDDD3AFC-D6B0-4D59-862E-D91CCA43E090.vcf?photo 404 (Not Found)

Also, when downloading the address book as a .vcf file after import+refresh, the downloaded address book has two contacts with the following PHOTO value:

PHOTO;VALUE=URI:data:image/jpeg;base64\,/9j/4AAQSkZJR...
PHOTO;VALUE=URI:data:image/jpeg\\;base64\,/9j/4AAQSkZJR...

So, the unescaped contact is exported unescaped again, but the escaped contact is exported with two \\ next to the ;.

It looks like both exports are incorrect, since according to vobject:

import vobject

card = vobject.vCard()

card.add('fn')
card.fn.value = "John Doe"

card.add('photo')
card.photo.params = {"VALUE": ["URI"]}
card.photo.value = "URI:data:image/jpeg;base64,/9j/4AAQSkZJR..."

print(card.serialize())

The serialization should be like (escaping both ; and ,):

BEGIN:VCARD
VERSION:3.0
FN:John Doe
PHOTO;VALUE=URI:URI:data:image/jpeg\;base64\,/9j/4AAQSkZJR...
END:VCARD

Expected behavior

• The correctly escaped .vcf (with \; in the photo URI) should be displayed correctly in the contact list.
• The exported .vcf should escape the \; too.

Actual behavior

• The correctly escaped .vcf (with \; in the photo URI) is not displayed correctly in the contact list.
• The exported .vcf does not escape \; , or it escapes it twice (if it was imported with the escaped \;.
