Can't edit dialogs

I use Arch Linux and whenever I try to edit dialog in LO it freezes, loading single core of the CPU to 100%, making me to force quit/kill the process. I’ve searched internet for the answers, but only found out Fedora bug (i also tried to use gtk2/gtk3, jdk/openjdk). If i try to edit dialog from any place other than macro editing app just freezes, if i try to edit dialog when a macro is open, it shows me the form, but still hangs. I tried latest versions both from repo and the official site.

Exact same issue here on Fedora 27.
Open the Basic editor works fine, but as soon as I doubleclick a newly created dialog, calc/basic freezes.
Reproduce;

  • Freshly open Calc 5.4.4.2-4.fc27
  • Menu Tools/Macro/Edit Macros
  • Menu Tools/Macro/Organize Dialogs
  • Add a new dialog anywhere (no matter if on mydialogs or in the new document)
  • doubleclick the new dialog
  • Calc freezes

Reopen a saved document with a dialog, I can sometimes edit the dialog, but eventually it freezes.
