Title:
  libglib2.0-dev does not include GLib's systemtap probe definitions

Status in “glib2.0” package in Ubuntu:
  Confirmed

Bug description:
  libglib2.0-dev does not include GLib's systemtap probe definitions, so
  it is impossible to perform GLib debugging using systemtap.

  Basically it means that /usr/share/systemtap/tapset/gobject.stp is
  missing (there is no package that provides such file).

  On Fedora, it comes as part of glib*-devel.

  Test case:

  
  $ stap --ldd debugging/alive.stp -c 'src/myapp -c config.xml'
  semantic error: probe point mismatch at position 0  (alternatives:
  __nfs __scheduler __signal __tcpmib __vm _linuxmib _signal _sunrpc
  _syscall _vfs begin begin(number) end end(number) error error(number)
  generic ioblock ioblock_trace ioscheduler ioscheduler_trace ipmib
  irq_handler kernel kprobe kprocess linuxmib module(string) nd_syscall
  netdev never nfs nfsd perf process process(number) process(string)
  procfs procfs(string) scheduler scsi signal socket softirq stap
  staprun sunrpc syscall tcp tcpmib timer tty udp vfs vm workqueue):
  identifier 'gobject' at debugging/alive.stp:2:7 while resolving probe
  point gobject.object_new
          source: probe gobject.object_new {
                        ^

  gobject.object_finalize
          source: probe gobject.object_finalize {
                        ^
  Pass 2: analysis failed.  Try again with another '--vp 01' option.

  
  script was:

  global alive
  probe gobject.object_new {
   alive[type]++
  }
  probe gobject.object_finalize {
   alive[type]--
  }
  probe end {
    printf ("Alive objects: \n")
    foreach (a in alive) {
     if (alive[a] > 0)
       printf ("%d\t%s\n", alive[a], a)
    }
  }
