This function is doing a couple of things now; you might want to split one or
more single-purposes helpers out (e.g., loading the file contents and returning
a string, or converting a line of the file into a CrashInfo struct).

   DCHECK(BrowserThread::CurrentlyOn(BrowserThread::FILE));
   FilePath crash_dir_path;
   PathService::Get(chrome::DIR_CRASH_DUMPS, &crash_dir_path);
   FilePath upload_log_path = crash_dir_path.AppendASCII("uploads.log");
   if (file_util::PathExists(upload_log_path)) {
     std::string contents;
+    std::vector<std::string> log_entries;
     file_util::ReadFileToString(upload_log_path, &contents);
-    base::SplitStringAlongWhitespace(contents, &log_entries_);
+    base::SplitStringAlongWhitespace(contents, &log_entries);
+
+    std::vector<std::string>::reverse_iterator i;
+    for (i = log_entries.rbegin(); i != log_entries.rend(); ++i) {
+      std::vector<std::string> components;
+      base::SplitString(*i, ',', &components);
+      // Skip any blank (or corrupted) lines.
+      if (components.size() != 2)
+        continue;
+      double seconds_since_epoch;
+      if (!base::StringToDouble(components[0], &seconds_since_epoch))
+        continue;
+      CrashInfo info(components[1],
+                     base::Time::FromDoubleT(seconds_since_epoch));
