Assertion (space > 0) failure during restore

FB5 debug build.
I created a database, filled it with some random data, created a backup. When I try to restore it, I get an assertion failure in RestoreRelationTask::fileReader.

gbak.exe -c bac_fb_5_0.fbk RES_FB_5_0.FDB -user SYSDBA -v
gbak:opened file bac_fb_5_0.fbk

Here's the backup file:
