[SyncEvolution] Fixing the Maemo backend

Hi,
I'm interested in getting the Maemo backend up and running again, to be
used in 'Maemo Leste' (Maemo 5, 100% open source, based on stable
Devuan/Debian).
The backend doesn't seem to be enabled by default in Debian, and it also
doesn't seem to build, when enabled explicitly. The dbus-1 cflags and
libs are missing (I added a call to pkg-config to work around this in
the maemo.am).
Then, I can see my calendar backends and invoke a sync, but it throws a
weird error when I try to sync like this:
> user at devuan:~$ syncevolution --sync refresh-from-client radicale calendar
This error shows up a lot (but maybe it is not harmful?):
> [ERROR] @default/radicalecal: basic_string::replace: __pos (which is 4294967295) > this->size() (which is 11)
Here's a slightly more verbose log, with most of my calendar events
removed, and two (first and last) left in place, but the description
modified.

The error is quite cryptic, and it's not clear to me what exactly is
throwing this error. Any help would be appreciated. I'd happy to help
fixing the problem.
Would it be helpful if I also included the html log file?
For the record, this is how I did the setup (this works on my Nokia N900
with the old Fremantle Maemo):

Any clues?
