btrfs qgroup show -pcre /

This morning my TW update failed on glibc-devel with the error message

Error: Subprocess failed. Error: RPM failed: error: unpacking of archive failed
on file /usr/include/bits/mqueue2.h: cpio: rename

And the kernel stack (truncating, copied by typing from screenshot):

WARNING: CPU: 2 PID: 25118 at fs/btrfs/qgroup.c:2936
btrfs_qgroup_free_mta+0x89/0x90 [btrfs]
CPU: 2 PID: 25118 Comm: rpm Tainted: G U W 4.10.10

btrfs_rename+0x184/0xd40 [btrfs]
vfs_rename+0x6ba/0x900
SyS_rename+0y3a6/0x3c0

I chose "ignore" option in zypper first, but aborted later after these errors
repeated, worrying that I might cause major corruption by continuing.

I tried btrfsck in rescue mode, but got an error there too:

...
checking root refs
checking quota groups
ERROR: out of memory
ERROR: Loading qgroups from disk: -2
ERROR: failed to check quota groups

I haven't conciously enabled quota support of this FS. output of btrfs qgroup
show -pcre / is attached.
