to overcome this bug,

The issue seems to be that the max size of an alias is 48, but the actual length can be more, so you need to delete the file, by file number + file incarnation.

Query this and find the files not removed by rm command:
SELECT 'alter diskgroup bk_group drop file ' --change as needed
|| '''+bk_group.' --change as needed
|| a.file_number
|| '.'
|| file_incarnation
|| ''';'
FROM v$asm_alias a, v$asm_file b
WHERE a.group_number = b.group_number
AND a.file_number = b.file_number
AND b.type = 'BACKUPSET'
AND a.name like 'backupname%' --change as needed
AND a.group_number = 3 --change as needed
ORDER by a.name
/

hope, this will helps you
