Subject: [PATCH] abrt-dump-xorg: support Xorg log backtraces prefixed by (EE)
The backtraces looks like
[ 60244.259] (EE) Backtrace
[ 60244.262] (EE) 0: /usr/libexec/Xorg (OsLookupColor+0x139) [0x59add9]
[ 60244.264] (EE) 1: /lib64/libc.so.6 (__restore_rt+0x0) [0x7f61be425b1f]
...
[ 60244.273] (EE) 13: ? (?+0x29) [0x29]
[ 60244.273] (EE)
[ 60244.273] (EE) Segmentation fault at address 0x7f61d93f6160
This format of Xorg log files was not supported by abrt-dump-xorg tool.
