this bug is already fixed in the latest relase candidates. Here is the fix:
I’m using carddavmate and caldavzap for a long time, and I recently
uncovered an issue:
When I modify my contacts from infcloud, some of my pictures, the ones
that get stored in png, have a field that looks like:
when exported. It seems like this kind of formatting is not supported,
so I guess it’s not a standard one: when synchronizing with other
clients, like the stock android app or khard, they crash or are unable
to display the picture.
As soon as I remove the "data:image/png;base64," part of the field, it
starts working again. Is it an issue with infcloud? Note that it used to
work for a long time without any issue, and quite recently I
simultaneously upgraded and migrated from caldavzap+carddavmate to
infcloud. I’m not absolutely sure what changed, but maybe it will ring a
bell to some of you?
