this is partially a duplicated of BUG188, who already has the patch uploaded.
will update it here too for completeness and to track it getting merged into
3.1.1 not to waste this bug then.
Created an attachment (id=152) [details] proposed backport patch for 3.1 also uploaded in BUG188
Commited revision 1657 for 3.1
When gmetad has a data_source which points to another gmetad's non-interactive port (8651 by default), it will segfault. gmetad debug output: [Test] is a 2.5 or later data stream hash_create size = 50 hash->size is 53 Found a <GRID>, depth is now 1 Segmentation fault strace output: 0xfee2b0b4) = ?
