Remote timer crash

Since a few online updates, remote timer crash when trying to add a remote timer.

For example, I have an xtrend ET6500 (OpenPli 4.0) with remote timer installed (trough the plugin panel). It is configured to store remote timer on a Vu+ Ultimo (OpenPli 4.0) using secure access (user/password). The Vu+ Ultimo is in the same lan 192.168.10.xxx, the webif port is not 80.

When I tried to add a remote timer, I get a green screen and a crash log you will find below.

I hope it will be easy to fix it.

PS : I tried also from the Vu+ Ultimo to the ET6500 with the same crash so it seems to be a bug for all Platform.
