calamares crashes when installing on logical volumes

[blueglyph]

In Manjaro 21.2.5, using calamares version 3.2.52.r10510.3e130c3e3

1. The installation crashes after manual partitioning, while trying to format the partitions.

• physical volumes were created (with pvcreate from the command-line)
• one logical group was created (with lgcreate)
• logical volumes were created (with lvcreate)

├─MANJ-swap 254:0    0     3G  0 lvm  
├─MANJ-sys  254:1    0    22G  0 lvm  
└─MANJ-home 254:2    0    18G  0 lvm  
sdb           8:16   0    15G  0 disk 
└─MANJ-home 254:2    0    18G  0 lvm

After selecting

• sys, asking to format it as ext4 and / mount point
• home, asking ext4 and /home mount point
• swap, asking linux-swap (no mount point)

and after validating the choices, calamares crashed.

Moreover, MANJ/sys had been removed from the group and completely deleted.

This makes it impossible to install Manjaro in a LVM system.

2. It is apparently possible to manage volume, but not to create physical volumes or volume groups

This can however be done manually from the command line, so this could only be a suggestion to add it.
