Package: gdb
Version: 8.2.50.20190222-1
Severity: minor

I'm debugging libnotmuch, which is C++ code calling glib, and see the following 
when attempting to examine a struct:


Breakpoint 1, _notmuch_message_file_parse (message=0x560a725d81a0) at 
lib/message-file.c:147
147         notmuch_status_t status = NOTMUCH_STATUS_SUCCESS;
(gdb) p *message->stream
$1 = {parent_object = {g_type_instance = {Python Exception <class 'gdb.error'> 
No type named TypeNode.: 
g_class = }, ref_count = 1, qdata = 0x0}, super_stream = 0x0, 
  position = 0, bound_start = 0, bound_end = -1}
(gdb) 

The underlying problem is actually missing debug symbols for glib
(installing libglib2.0-0-dbgsym fixes it). It would be great if the
error message was more helpful.
